did you clear the fault code 1st ?

[big_kev]

Have you cleared the fault code first........if not this may still be the original fault showing.

yeah sorry there was 5 fault codes that where cleared, so reset then plugged in vag-com and every time engine is started registers the same fault code

Possibly a defective glowplug or more likely the wrong one for the booster and its touching the frame instead of being insulated.

ok will check it out, was actually a garage that fitted this so maybe shoiuld get them to follow up!!!!!

 

So most likley it is still a problem with the glowplug yes???

Certainly! If you pay for something it should be done right! "Short to ground" can only be incorrect or badly fitted plug or a wiring fault. The latter being reasonably unlikely unless they've caught it whilst putting it back together.

mmm me wonders if when you take it back they come out with the old chesnut,

you need a new booster heater????

Was not a fraud garage was my local small garage what i always use, when i told them to replace aux plug got a confused look i had to explain to them what it was, it went in originally for a front end wobble(now repaired), but knew about the plug problems(from here),and because brother-in-law had a alhambra which he replaced the plug in.

Intrestingly they said there was no fault codes showing when they replaced plug soon as i plugged vag-com in found the 5 that needed resetting.

check they actually fitted the correct plug, they should have paperwork to prove they got the plug in for that job, they could have fitted any glow plug that looked similar !

a lot of these garages have never seen or heard one of these heaters and know nothing about them.

Had my aux heater apart after heavy smoke from the unit exaust & failed start ups. I removed the glow plug, cleaned it with wet & dry sanding paper. on refitting, noticed the two teminals that fit to the top of the plug, so close together that you have to be carefull that you dont have them touching creating a short circuit or crossing current in damp conditions etc My heater is now working fine..... best of luck folks :huh:
