Over heating 170 TDI

TDI 170 now back with VW dealer only 800 miles on the clock. despite doing short runs (7 miles or so no air con on) when you leave the car fans would continue to run for some time after (no have not been booting it) but radiator is stone cold and a strong smell of hot rubber hoses.
Does this sound familiar to any one else.
I think the thermostat is not opening or sticking as there are times when the temperature gauge will plummet.
Just to add insult to injury was told they did not have a car to loan me as VW will have to supply one and that will take another day. Asked if some one could give me a lift down the road was told no so had to walk 4 ½ miles home in the rain or wait an hour for the next bus . I walked.
Is this normal practise for VW agents seems once you have paid for your car that's were the help ends.

That is disgusting service Peter, I would be on the phone or be writing a letter to VW UK Customer Services about that ASAP!! Hope the car gets sorted pronto. I have not had any sign of this on my 170 TDi, and I have now got 3800 miles on the clock.

My TDI 170 has done 3000 miles now - have had the car fan issue 1 time, where it continued to run 5 mins after i turned off the car.
Havent seen it since, and i believe it to be normal....havent consulted the dealer about it though

Hi Trirx. Have had the "call come and collect your car " on the desk of the service reception was a quote from the promise.
Having the keys in my hand i asked why i did not get at least a lift home and was told that if you want this service you must give them 7 to 10 days notice.
In a nut shell if your car develops a falt and you book it in and cant give them notice before it developes you have to make your own transport arrangements unless you get VW to arrange a car and they need 48 hours.

sorry Peter but what a load of twaddle! mine was in for diagnostics not to be kept for any length of time & I was waiting for it, when they decided it wasn't driveable until the new shock came in they didn't have a problem at all arranging a driver to drop me at work (was picked up in less than 10 minutes).
a complaint should be made to vw uk because they have gone against the servicing promise & that is a load of rubbish that they have spouted to try & get out of it.

Hi trix gessed as much, have been working on a letter to send off but at the end of the day i have had a bad experience with this dealer almost from the start and I think the best approach is not to give them any or my trade, it does leave them free to continue to give poor service but I think complaining will not make any difference, its a shame you cant do more by having a list of dealers that don't come up to par (name and shame) so we all can make a choice weather to use a particular garage. This can work both ways to recommend also.

It is worth complaining, cos someone will at M.K. will take notice as the promise is VW, not dealership based. Watch your timing though as you want your car sorted. Dealers don't like being "talked to".

Just to throw my experiences into this one...
Today after my typical journey home I switched off the engine and the fan ran on for in excess of five minutes.
This has happened on one other occasion.
Mine is 140 TDi
Anyone else seen this?

Hi you expect the fan to run if you have been in traffic or may be been driving hard or the air con has been on,the thing that gave me consern was that the rad was cold and a strong smell of hot steel and rubber and the fan running.

My 140 TDi has done it twice in 3 months and I haven't pushed it hard, driven it in traffic or had the AC on in those two occasions. First time, I started the engine shut on/off and it stopped but the second time I left it to see what happens - the fan stopped in about 7 min. My dad's Audi A4 143TDi does the exact same thing and the blokes from the Audi dealership told him there is no problem (may be because he couldn't replicate the problem in front of them). In fact many people encounter this issue on the Roc and some are serious about it but in my opinion, it's not a big deal - for now

Hi Peter VW,
I totally get what you're saying and it does not sound right. Your diagnosis of a faulty therostat I recon is on the button and it should be checked out. If the fan is running it should be pumping bloody hot water through the rad so a cold rad and fan running spells trouble.

Hi my dealer says that they have checked this fault out but can not replicate the problems I have had and that its working within parameters, wile I understand the problems of rectifying a irregular fault its just as hard for me to rush to the garage with an over heating engine. In any case they will not look there and then but book it in another day which is what happened this time.
To be honest it would be better if I got a new stat and fit it myself

I believe this is normal. I spoke to the senior tech at my dealership and he confirmed it. It is the first stage of DPF regeneration. It also happens periodically when driving but its hard to notice. Here is what I noticed:-
" I stopped car at house both and fans were running, RPM at 950 lifted bonnet engine very hot. Also if you put your hand over the exhaust the air coming out is very hot (due to the fuel getting burnt in the DPF) I believe this is normal. Just not sure why I havn't noticed this in the first 4.5K miles. Maybe just timing on my part."
I was told that if the DPF starts to get sooted up the engine management kicks in and temporarily changes the engine timing. This I believe allows the engine to run hotter and some fuel may actually burn in the DPF. This changes the soot to ash thereby cleaning the DPF. The next stage, if this doesn't clear it the DPF warning light may come on and you should take the car for a 15min run keeping the revs at about 2000RPM on a light throttle.
If you do a lot of moterway driving you may not have an issue.
The price for having a smokeless diesel!

Hi This could be it, i do a short run so the stat may have not opend hence the cold rad but the dpf has gone into a clean Cycle so the filter starts to heat up which is were the smell of hot metal comes from.
Fantastic
Well done Digiman why cant the dealer work this one out, I think guys that really knows what’s going on under the bonnet of the car are few and far between. Congratulate your man for me.

My 140 TDI has done this a couple of times but only when it was new...I was taking it easy with it so I could imagine all the build up of soot in the DPF caused this to happen, but now using all the rev's it's never happened again.
Over the years I've had diesels I've found it does them no harm at all to give them a good thrashing now and again as it clears them out, the Scirocco is no different it'll get the same treatment as all my other cars did.

My 140 TDI does this now an again and the first time it did I asked on here if it was normal. I'm pretty sure it even mentions the fan staying on in the manual too. Only seems to happen on mine after short journeys.

Apologies for butting in on this thread, but did not Peter W say in the original message that this happens "when I leave the car". I assume from this that the engine is at that point switched off so there will be no regen going on. If there's no regen and the fan is on, surely the thermostat will be open and the rad should be hot!

Hi no the fan would be runing on after the engine was switched off but the rad was cold, I think the explanation from digiman is the most plausible, the fan runs because the filter is cleaning its self and gets hot as a consequence.
Thanks for your input I am amazed at the wealth of knowledge that is available on this site.
