Hi Mark....welcome to the Forum Look forward to seeing some pics of this lovely rare car Cheers, Trevor

Hi Karen I would definitely consider repairing the Z3....after all, they are going up in value. Not sure which engine size it is and also how many cylinders? If it has the four cylinder engine then these are cheap and plentiful and very easy to fit a new one....all in imagine you would be looking to fit a secondhand engine for around £650 to £750. The alternative is to replace the piston or rings which again is an easy job on these engines but I would have a garage Leak Test the cylinder to determine whether it is a defective piston or valve (simple job to carry out with compressed air and see where it leaks from). However, if it is the 6 cylinder engine as Dave has already talked about then costs would be considerably higher (much more complex engine). I'm hanging onto my Z3 for both sentimental and also financial reasons and cannot imagine a day where I will part with it Let us know how you get on with it Cheers . Trevor

Hi Adam Usually if the MAF is disconnected then the system runs on a default setting (which is usually quite acceptable to drive on) so it confirms the MAF as being faulty. I would replace it and then see how the other codes appear, or not as the case may be

Hi Jonathon....welcome to the Forums Great looking Bimmer.....Enjoy! Cheers . Trevor

Hi Chris....welcome to the Forums Good to have you onboard Cheers, Trevor

Hi Charlie....welcome to the Forums

It definitely sounds like turbo boost pressure leaking from one of the hoses or intercooler....you would have to have someone on the throttle holding it to boost pressure while you listen to where its coming from.
