You probably already know this but the tracking should be checked after work on the control arms. I have also seen it reported on this forum that the poly bushes make the car more sensitive to correct/exact wheel balancing. If the vibration/judder occurs only when braking, I agree with Bladerunner 9...

I seem to recall a Sunbeam Alpine? in the first film Dr No so the Z3 can't possibly be claimed to be the worst

Del

Many have reported a similar fault which turned out to be a camshaft position sensor. However, best to plug the car into a diagnostic fault finder. I have a local garage that only charges £20 + VAT for doing this. If you want to do it regularly, there are plenty of inexpensive fault code readers on ...

80K is not high mileage at all. If it was mine and there was a question over whether servicing had been kept up to date, i would work my way through all the usual things eg nice new oil/filter, plugs, air filter, check brakes/pads, change brake fluid & coolant.

Tracey has given it a regler service

Ball park average loss = 1% per year. There are a lot of variables and with an engine that has been really looked after eg oil changes twice as frequently as suggested by the manuafacturer, the loss can be less.

I can categorically confirm that BMW MTF LT2 is:- GL4 gear oil Viscosity SAE 75W/80 Fully synthetic If you do a Google search on Google images you will find that lots of people have actually posted pictures of the BMW containers that actually specify these charactoristics for BMW MTF LT2. MTF LT1 is...

I appreciate that owners cherish their Z3s and should service them in a way that gives them best peace of mind. Personally, I am not at all happy to keep GL4 gear oil in my gearbox for 10+ years. Furthermore, in my opinion for my own car, I find the suggestion that “special BMW” synthetic engine oil...

Del

The problem is that gear oils have improved/advanced since the stickers were stuck on the gearboxes in the 1990s but nobody really wants to override these stickers. The result is that in 2012 confusion reigns. MTF LT 1 is claimed by many to have been fully synthetic GL4 75W80 gear oil.

Attached is a (poor) picture of the edging strips inside my car cover. I have been studying Gill’s damage photos above. I would stress that I am in no way doubting the damage caused by the cover.

I've enjoyed reading this thread lads - nice work. Needs a bit of carbon fibre somewhere under the bonnet to finish things off.

Good stuff - I use Fabsil Gold. Simply paint it on with a brush - less mess than a spray.

is your's the M54 engine?

If so, the attached looks like it may help a bit.

Sorry to hear your problem is persisting. I would have expected the cam position sensor to just be covered in oil not gummed up with a load of crud. You mentioned your PCV/CVV looked gummed up and that the car momentarily ran better after removing it - I'm not sure if they can be succesfully cleaned...

I suspect the firm has had different sources for the magnetic strip and the two experiences above relate to a bad batch. There can be no other reason for some having had no problems whatsoever (me included) and now two other forum members who clearly had problems quite quickly. If there was a faulty...

Hi and welcome. Nice car and nice price. The 1.9s go alright when all the vacuum pipework (M44 engine) is in good condition and the engine serviced. As you say the fuel economy is surprisingly good. I'm happy with mine.

Del

SNAP! Similar model to mine - welcome to the forum.

Del

Car looks in lovely condition and I like the choice of original BMW wheels - classic German, five spoke style also echoed by AMG/Porsche - same as mine.

Del

Whilst I don’t like to see prices go down, you can’t buck the market and in these recessionary times the wider public must perceive Z3s as old-fashioned, impractical, gas-guzzlers for which spare parts are costly.

Del

As it cuts in at around 3000 RPM it hints at the possibility of it being resonance/vibration related as opposed to a bearing. However, as suggested already, it is impossible to diagnose these “noises” over a forum and it would be wise to get a second opinion “on the spot” so to speak. Like me, do yo...

I'm drooling over the carbon fibre. Wouldn't mind just a bit in mine to break up the expanse of cheap black plastic.

There's a lot of fault codes popping up which tends to make it implausible that several sensors are all going faulty together. I am not an expert for this engine, my simple minded view is that an intermittent problem tends to point to something electrical/sensor related as opposed to a physical prob...

Could be lots of simple, harmless things. I had something similar when my gearbox exhaust mounting rusted away - there was a strange tinkling rattle at certain revs. The bottom half of this bracket/shackle commonly rusts away with age.

As a fellow M44 owner, all good stuff from the contributors above. The temperature problem certainly sounds just like the same thermostat issue I had when I bought mine in 2011. After changing it, the gauge now moves quickly to 12 o’clock and sticks there. You can now roast chestnuts in front of my ...

My understanding on tuning/re-mapping is that it was not simply a case of removing the MAF but replacing it with an alternative sensor in the manifold – which allegedly does not restrict airflow to the same extent. Further, I understood that opinions differ on this with some tuning firms preferring ...

Del

When an important sensor like a MAF is disconnected the ECU goes into “default” mode which some people term “limp home mode” or “run safe mode”. Performance is normally jaded across the rev range whereas when the ECU is receiving, correct variable sensor feedback it will be allowing the engine to pe...

The prices for the new parts quoted by your Indy were a bit on the high side. I rate carparts4less.co.uk which is the internet trading arm of Europarts. Your Bosch MAF is £138 and Bosch lamdas start at around £50.

Del

Sorry to hear you are still having problems. You must have the M43 engine (pre and post cat lambdas). It would be very bad luck to have had a bad camshaft position sensor (previously replaced), two bad lambda sensors and a bad MAF. I would try a cold start with the MAF disconnected so that the ECU g...

Bagged yourself a bargain there! Hopefully it enabled you to keep a bit aside to spend on fixing snags and gettig her up to your requirements. 85,000 miles is nothing on one of these engines if its been looked after with oil changes.

That's good news - the Cat is probably perfectly OK. The OE E36 cats are known amongst MOT testers to take longer to get to their correct, working heat. Under the fast idle test they stick at around 0.5 Co for ages and then start to steadily drop to the required 0.2 or less. The car should be runnin...

I’ve used mine a lot this year and found it great and extremely good value for money. I’ve had no issue with anything even approaching the magnetic strip problem mentioned above. The strip in question is about one inch wide and is hard and plastic in character and not soft rubber. This may have been...

Hi Doug

Are you saying that all the fault codes have now cleared and the car is running fine but the CO readings are still high?

The Bosch part number for your 1999 M43 MAF is 0280217124. REALOEM.com shows an item numbered 11 on the part diagram but doesn't list a separate air temperature sensor. It must be a generic diagram including both M44 & M43 engine variants. You have the more modern set up where the temperature se...

Panic over - making progress – established it’s the later 1.9 M43 engine. I know much less about this engine but suspect it has a different MAF to the M44 and possibly has an integrated air temperature sensor – others on the forum will know for sure. I would still have the same suspicion about the f...

Ooooh – ALARM BELLS - I’d be cautious on that lack of an air temperature sensor just in case a previous owner has fitted an air filter box from a different model. I’d recommend you put your last 7 digits of your VIN number into Realoem.com (Fuel preparation system) – (intake silencer) and check if y...

Hi Laurieh Sorry to hear you are still having this cold start problem with your M44. Many initial suggestions for a rough idle and a batch of codes being thrown will, quite rightly, be to check for vacuum leaks. The M44 certainly has a lot of vacuum pipework. If you are absolutely happy that all you...

Tend to agree with Gazza. A friend of mine has a a MGTF and prices for those have plummeted. I'm sure the comment above is a crafty ploy by Mr Shultz to make Z owners depressed, sale their cars cheaply to him so he could make millions and retire to Spain at the age of 35!

Del

Am I right in thinking you have the 1.9 M44 engine? If so, your ECU is the Bosch Motronic 5.2. My understanding is that fault code 112 under this particular ECU stands for “camshaft position sensor”. You mentioned the term “Phase Sensor” earlier. I also understand that the term phase sensor is “diag...

If you have the M44 engine, trying to drain the actual engine block is a hassle as the underside, stretching to the rear of the gearbox, is unaccessible unless you remove the large plastic cover. The BMW technicians would also certainly just drain the radiator once and then add the new coolant. Doug...

Del

My educated guess would be with Robert T - the camshaft position sensor. Did you get a numerical error number 112 as well?

Del

Hi Spikey

OEM BMW Camshaft Position Sensor for the M44 is part number B12.14.1.743.072 and if you're feeling fussy a new rubber O ring B12.14.1.748.398 (under £1).

Yep – these little cars scrub up well and probably punch above their weight in the looks/prestige department. You won’t be disappointed with the gear knob.
