I’m such a Wally… as I was just test fitting the lower timing cover to align marks I hadn’t put the 10mm bolts on the cover all the way in. The squeaky noise was the back of the crank pulley against the 10mm bolts. A massive relief as it now turns nicely with no noise.

I’ve just changed the timing belt on my 1.8T Audi TT MK1. I got the engine to TDC, marked the belt and refitted in reverse. When rotating the crank by hand, both TDC lines match after two rotations of the engine so all good there, but the crank sounds squeaky/creaky when rotating by hand. It’s...

I think the oil leak is from where the engine block meets the cylinder head (ouch). I don’t have oil mixing with the coolant, it’s not overheating or anything like that. If it is from here am I right in saying the only way to fix this would be to have the head removed, skimmed and resealed (as...

This will be a leak AFTER the MAF (mass air flow sensor). It means the system is getting more air than the MAF is measuring entering the intake system. The ECU is constantly trying to achieve stoichiometry (lambda) of the correct air and fuel ratio. Since it’s getting extra unmetered air it...

Thanks for the reply. Intercooler pipes look fine, and no sign of gearbox leak. Is there a seal on the propshaft? Wondering if this could be leaking?

I have an A3 2007 2.0 TFSI Quattro I’ve got a slight oil leak but can’t work out where from. There is wet oil on the heat shield around the cat (directly above the propshaft), there is oil on the subframe, electric steering rack, and some oil on the banjo bolt of the turbo. I’ve laid...

Yes but you’ve got to get the ****** out first and then refit it

Check your tension on the belt, has the belt been put back on too tightly?

Yes, whilst it’s running. I mean as in the video you posted. I’ll do it with my car to see if it does anything different

I mean just pull it out slightly not completely remove. I’d get the gasket changed. If I remember correctly it’s £20 ish from audi

I’ll remove my dipstick while the engine is running and see what it does for comparison.

Was the gasket changed when the pcv valve was replaced? I wouldn’t rule out a faulty new pcv valve. I think I have something similar. Replaced my pcv and gasket with a new genuine audi part (not cause it was faulty but more as a preventative service part) and now I’m getting a little oil mist...

Removing the dipstick or oil filler cap creates a vacuum leak. Similarly, if either aren’t sealing or leaking slightly this will also create a vacuum leak. These vac leaks are adapted by the ECU overtime (evident in the long term and short term fuel trims LTFT / STFT). The ECU can only make...

This unfortunately sounds like a problem with the mechatronics unit on the gearbox. Hopefully the garage will cover the repair because otherwise I believe it’s an expensive 2k plus job. Google mechatronics failure and you’ll probably have most of the symptoms. It gets so bad that it will...

It’s weird you say that actually as I had an intermittent fault on vcds flag up for the N80 evap valve. It’s also making noticeable clicking at idle, which I understand is normal to some degree but maybe it’s on its way out. Thanks for that

when the engine is warm, with the windows down or heaters on I can smell what I believe is oil vapour. I can also smell the same smell from under the bonnet. I’ve checked all breather hoses etc and can’t see/smell any leaks. No signs of oil and no leaks on the floor. It’s had a new genuine...

What’s the mileage please and has the timing belt been done?

Where did you get the walnut blast for £200? Seems a good price for the work involved
