I have 2 cars from the VW/Audi group and like to do DIY myself.

My current problem is on a 2007 2.0TDI which is a PD engine - I think its the BKD.

I had great difficulty getting enough room to fit a new brake servo and had to lower the engine. New brake servo fitted but while stripped down to fit Servo I fitted new timing belt, Water pump, idler wheels, tensioner and alternator belt and tensioner,

To do this i had to disconnect the fuel pipes.

Car now starts for a second or 2 then shuts down. When running it reved up OK and sounded fine. Felt like fuel starvation. Check diesel tank lift pump and it only gets an initial pulse. Took a 12V supply to lift pump and its working fine. I checked flow by disconnecting the diesel return pipe at the filter.

It appears the ECU is shutting the engine down either a stupid fault on my part a cable damaged or disconnected or by coincidence a new fault.

Decided to invest in a "good" OBD2 scanner to look for codes. Currently thinking of buying the OTOFIX D1 Lite but note that some scanners cost up to £1500. The 2026 version resets some 40 error codes and costs £309 on e bay.

Any comments on possible causes and my choice of Scanner be appreciated?

Being retired I have the time and prefer to spend money on equipment rather that official garage costs! I am a reasonably competent DIY mechanic as years ago I paid for my 4year engineering degree by repairing cars.

Bought scanner to get " camshaft sensor fault !"

For BMN dohc 170bhp engine on asking for engine faults on AI got message that fuel starvation can cause a mis- diagnosed fault code of "camshaft sensor failure"

Be aware of this in event of diesel lift pump failure or in my case failure to bleed the fuel lines.

Should correct 1st post Engine is 2007 BMN 2.0TDI dohc 170bhp fitted to many audi's, and VAG group cars during this period

It's unfortunate nobody has replied, but you seem to be coping well.

Hi if you want to buy a proper scanner software buy VCDS its pretty cheap at the moment and with life time updates its worth a look.

If you have 2 VAG cars, then VCDS every time. You can get 3-VIN licence from Gendan for £222, then all you need is an old laptop to run it. That gives you access to Ross-tech forum for more detailed answers if you load scans, lifetime software updates, etc.

On new VAG cars such as Golf Mk 8 for example, they have started to limit accessibility, such as using dealer level ODIS software. In addition, what was pay-to-view erWin is dealer only now. Start of things to come.
