Hi guys,

Bought my first GTi-6 last weekend (will get some pics up etc soon) and totally loving it! However, do have a couple of things I'd like to run past you guys...

1) When I start the car from cold each morning, it can be a little hesitant and jumpy for a couple of mins. After this it is fine, no problems at all and no lights show on dash, just seems to be first couple of mins each morning. Any suggestions?

2) Also, on a couple of occasions, have started the car in the morning (when cold) and when I've pulled up at the first junction, it has dropped in revs and cut out. Started fine after. It has only done it to me twice from memory, and only when it was cold. But once it did cut out, it started again fine and didn't do it for the rest of the journey.

The revs idle nicely most of the time, but every now and then if I go to park up, I put my foot on the clutch and I'm sure the revs sometimes pick up momentarily and then die back down again. It could just be me, but I'm certain it pops up and settles again.

As above, the hesitation and cutting out has only happened when the car was first started from cold, and within a couple of mins it is running absolutely sweet and doesn't cause any problems at all, apart from the idle sometimes dipping and coming back up again. But once the car is sat still and the idle has settled, it is fine.

Could all these problems be linked?

Appreciate any help guys

I agree with the above.

New coolant temp sensor is about £13, so not too bad. The ICV will most likely need a clean, it's a very simple task and is explained in great detail in the FAQ section.

blue is for the gauge green for the ecu.

its 19mm

ICAV, 2x10mm bolts, unplug it and it comes out. undo the 2 screws holding it to the housing and clean away then stick some good grease in the middle and bobs your teapot

If cleaning and/or replacing the ICV doesn't fix it try changing the MAP sensor - the long, black, plastic sensor beside the top of the throttle body, held in by 1 bolt.

The MAP sensor works along side the throttle position sensor to determine the load on the engine. The engine will run, albeit temperamentally, without it plugged in.

Yes it will run, but it won't idle well/at all.

You could remove the plugs in the morning after standing over night and see if there is any condensation/damp on them before starting engine

Or a 'sniff' test of the gasses in the coolant system by a garage is pretty accurate

Has the car got any history of the head being removed?

As the original gasket will now be over 10 years old,and they rot due to the fact they are multi layer steel gaskets as standard on this engine

No, can't say I've ever seen any smoke at all to be honest.

Nope, never needed to top it up.

I put some in the other day, as I changed the temp sensor so obviously lost a bit of coolant when I took it out to put a new one in.

Otherwise it seems fine.

I had a split pipe too.
There quite an easy way of fixing them which i will explain.
Where the little pipe joins to the big one, it will likely be spliting where they actually touch.
Tear the little one off fully so you are left with it completely detached.
get a serated blade, and cut two small 2cm lines outwardly on opposite side of the hole in the big pipe.
This will allow you to force the small pipe through the big one so that it is held in place.
Get some thick tape of sealant can seal the outside of the tube.
Wait for it to dry.
Job jobbed.

Any updates on this? My ICV will intermittently fail completely about once every 2 months and the car will stall at a junction, the rest of the time it is not quite right e.g. the revs will fall below tickover then rise again before settling.

In the past 2 days a new problem has arisen whereby for the first 30 seconds or so the car will stutter a bit and not increase in revs and then suddenly take off. I have a theory (perhaps some people will be able to chuck in their thoughts) that the ICV is on it's last legs and sometimes doesn't operate so the air mixture is completely wrong to what the ECU thinks it should be.

Head was rebuilt 2 years ago so very unlikely to be head gasket. MAP sensor has been checked with a multimeter and seems to be ok. Other thing is TPS which I haven't had a chance to check yet, seems unlikely though as it runs like a dream otherwise. Also passed MOT 2 weeks ago to rule out lambda.
