My Galaxy 1.9 115 has suffered terribly from lack of power over the last few months, Its been regulaly serviced as it does many miles annually. I have tried disconnecting the mass air flow sensor, its been cleaned, and makes no difference wether it is connected or not.
The problem occasionally improves but for a very short time.
It does need the thermostat replacing as runs cool in the winter but fine in summer. The glow plug refuses to stay lit on intial cold start and the engine will rapidly rev up on start, but once its warmed, the glow plug light stays on for about 7 secs and it starts fine.
Help please..

Hi and welcome to the forum

Would be useful to see if any faults are logged, sounds like you may have a faulty temperature sensor this sends signals to the engine ECU and also works the temperature gauge this can cause the high tickover when cold.

Slow warm up in winter may be due to booster heater not working (commom problem)

As for the MAF that may also be faulty as you have said it dont make any difference if connected or not.

So to summarise get youself a VAGcom lead + software or maybe a member near you will do a scan for you see what comes up, there's lots help on here or you can do a search or look in the FAQ's

Thank you very much. I would be keen to buy the cable etc and do it myself, I'm just very unsure of which software I would need as the ones I have seen only cover diesel engines from 04 onwards.

you could check the boot for excess sausages, and try jacking up the fusebox, has been known to help :)lol

I can't comment on the Proscan as I haven't used it.
