#1: Overheating 1.6 HDi GTi Author: scottwyatt68, Location: KentPosted: Thu Oct 20, 2011 2:51 am ---- Morning All,
My wife has a 1.6 HDi GTi - its a great car and she loves it, but we're having a problem with overheating. It seems to happen more when reused shortly after another run. The cooling fan kicks in on switching the engine off, which is fine, but this is draining the battery and causing starting problems.
Its had a new battery and coolant levels are fine. Also been serviced, so it has new oil at correct level. Any ideas?
Thanks,
Scott

other than this all I can say is make sure there's no leaks with coolant etc.
worst comes to worst to it to a qualified mechanic

I think your DPF may be regenerating and that's whats causing the fans to kick in. Fans should go off with the ignition though.

Cooling fan running when ignition turned off means the FAP system is trying to do a regen, its designed to do that.
The cooling fan should switch off after a maximum of 15 minutes.
#5: Re: Overheating 1.6 HDi GTi Author: scottwyatt68, Location: KentPosted: Thu Oct 20, 2011 11:33 am ---- Thanks all. I have a feeling it might be radiator. Fan stays on when ignition is off and thats what's draining the battery. She does short runs every day with occasional distance, so not great for battery, but on a long run the temp creeps up past 90 degrees and gets hotter as it goes faster, so definitely something in the cooling, just don't know how best to sort!
#6: Re: Overheating 1.6 HDi GTi Author: Lee, Location: EnglandPosted: Thu Oct 20, 2011 11:50 am ---- Short runs are the worst thing ever for the 1.6HDi
My advice, sell the car and get something more suitable for your needs.

Its trying to do a regen as it has a FAP / DPF fitted.

Which temp gauge are you looking at?
Water temp is at bottom of rev counter on the 5 dial cluster
The temp gauge on the right is for the OIL temp

The real issue is why it gets so hot on everyday use when most cars I know sit static at operating temp and don't move unless there's a problem. I didn't really want to get into changing everything to find out what it is by a process of elimination, but looks like I might have to, so I'll start with a rad flush. Thanks.

Have you not paid any attention to what MrBSI has said? Its your DIESEL PARTICULATE FILTER that is trying to regenerate itself and that is why your oil temperature is rising. It has nothing to do with the radiator.
You are doing too many short low speed journeys causing the DPF to become blocked. Go and take the car for an hours drive up the motorway, high gear, low revs and use as much electrical equipment as you can.

#13: Re: Overheating 1.6 HDi GTi Author: marc206, Location: Bourne, LincsPosted: Fri Oct 21, 2011 3:28 pm ---- there was something about that disel filter on watchdog. gets clogged up with all the crap if you don't go fast enough. they did say take it out for 30 mins at above 50 should clean it, otherwise it'll cost you an arm and a leg to get it fixed everytime.
