Another day another problem!!

[dub268]

Stilling having problems with car stalling when driving, so hooked it up to vagcom again last night and found

Address 01: Engine
   Controller: 06A 906 018 CG
   Component: 1.8L R4/5VT MOTR HS D02
   Coding: 04000
   Shop #: WSC 00028
2 Faults Found:
16500 - Engine Coolant Temp. Sensor (G62): Implausible Signal
            P0116 - 35-10 - - - Intermittent
00544 - Maximum Boost Pressure Exceeded
            35-10 - - - Intermittent
Readiness: N/A

which is the same as last time, so ive done a little search around the net and found that 00544 is linked to a fault n75, would the n75 cause the engine to stall?
If it is n75 which one is best to replace mine, as ive read J & H valves seam to be upgrade valves and c is stock replacement and where's the best place to get one from?

I would replace the temp sender as a first step.

I'll try get one over the weekend see what happens.

Could still be the maf too, have you tried unplugging it?

No im guess that is the lambda spitting it's dummy  and stalling the engine, any idea how much new sensor is and best place to get on from and is it easy enough to replace?

[houston]

can get universal ones for about 20 quid from a motor factors, there easy to change if it comes out ok, but most of the time they can be a pig, best off just hammering a socket over the old sensor so you have more of a grip to take it off, wd40 it the night before your gonna work on it
