Cam belt out of timing

BJohan said:
I disconnected the cables to the EGR valve and the engine runs perfectly! Even though I have a new EGR valve there must be something wrong with it. A mechanic said it has to be a Pierburg original EGR. Nothing else works. My EGR is not Pierburg. Can that be the problem? Do anyone have experience from another brand of EGR?
Now the check engine light is on so I guess it will not pass MOT without an EGR. Should I replace it with a Pierburg?

There a quite a few different suppliers of EGR valves that claim to be suitable for a 1.4 AUA/BBY petrol. I find it difficult to believe that only one supplier's valve will function correctly. There are two types of EGR valve, pneumatic and electric. Yours should be pneumatic I believe, which should mean that any "suitable" valve is more likely to be compatible. Is it possible that you have a vacuum leak rather than a faulty valve?

I believe. Well know issue that only the original egr valves work in these engines

It's electric. The hose connection leads to a small filter.

Pierburg egr seems available in germany for under 80euro. Nice then, one step closer to the solution hopfully. :).
 
Autodoc is never the cheapest place, as one can see also in this case, but they have often many brands to choose from at least.
 
I ended up buying a Pierburg EGR valve on Amazon. They have just started up in Sweden and have free delivery and great price. I replaced the EGR and the car runs beautifully. So, to sum up, my problems was caused by two things:
1. The cambelt was out of timing, probably slipped a gear
2. I had the wrong EGR valve even if it was new. I replaced it with a genuine Pierburg and all problems are gone.

Thanks for the feedback, glad you got it sorted.
Could you share the amazon price for reference?
 
I have similar problem with mine AUA 2001. How can you check if it has skipped a tooth? I have never got a fault code for the egr valve.
 
Line up the crank shaft timing mark and trial fit the two cam locking pins

It’s unlikely that the ecu will log anything if it’s a single tooth out. It has a tolerance and a tooth is within the tolerance. However having the timing correct on BOTH cams is important for correct running so well worth having it checked
