middle one is a crank sensor fault code and first one is an electrical fault, http://wiki.ross-tech.com/wiki/index.php/18051/P1643/005699

try this website

Read my current thread about the engine speed sensor, otherwise known as the crankshaft possition sensor, http://briskoda.net/forums/topic/184320-octavia-ii-19tdi-pd-engine-speed-sensor/ this might help with that problem.

I think the oxygen sensor may be part of the MAF sensor, if so i found a guide online on how to remove and clean them (saves buying a new one).

Cheers

Does the car run?

I would start by replacing crank sensor then clear the codes and see what returns. The top code maybe present due to the other codes. Any exhaust mods?

Hi

The car runs but only revs to 3500rpm.

There are no mods as completely standard.

What do you think?

Thanks

Hi

Just so you all know it was the crank shaft sensor!

Now it goes like a rocket with better fuel consumption!
