I've experienced similar on my 1.4 petrol, after some drive the temp normally moves between 85-90C, now its 75-85C.
My TDI eventually warms up to 80 degrees or more in those conditions and hence the needle sits at 90. I think your thermostat or possibly the sender is starting to fail.
My normally rock steady tdi 75 Tonka gravitates between 86-91C (I can be exact as have colour DIS) when up to temperature and Is normally up to temperature within 5 miles or so. When under constant load (up hills or being driven quickly- mainly the former!) over the last few days it’s behaved as normal, but otherwise it’s been stopping down to 60-70 for much of the time.
That's not bad at all. And a free cup of coffee!
My 1.4 petrol is also taking longer to get up to 90C and fuel economy is down by c20%
Mine has been struggling to get up to temp on my morning commute this week - temps of -6C, heater working hard and slower speeds have all slowed warm up, so one morning it never quite got to 90! I did wonder if the thermostat might be going, but on reflection think it's just the weather!
Well if your normal fuel consumption is > 60 mpg and you regularily see a vertical needle temp reading i'm wandering if there is something slightly adrift with my thermostat.
RE TempsIt was nice and warm where you were! Try -11.5°C this morning round my way
The 1.4TDI is so efficient that it produces very little heat on its own. This makes it very slow to warm up when it's cold outside, sometimes it never even gets to 90°. The AMF engine was fitted with a Webasto pre-heater until about mid-2002 that warms the coolant and hence both the cabin and the engine. Later AMFs, and all BHCs and ATLs, have just an electric heater for the cabin instead, leaving the engine to fend for itself for coolant temperature.
When the outside temperature is +8°, which is just above the cut-in point for the Webasto on mine, it can take 20 miles of mixed driving on my commute to get to 90° on the gauge. Once there it stays there, but I suspect it would never manage it in these temperatures without the Webasto. This morning I did have to sit in a queue for a little while before the thermostat had opened and even with the Webasto running it dropped from about 85° to about 70°C on the temp gauge. I believe in the operational specs for the Webasto, one of the parameters that have to be fulfilled for it to turn off is that the engine is at least 70°C. Presumably it can't guarantee to output any more than that in the coldest of conditions.
I have exact spec car inside and out, red with akoya. Nice one
When I was at the Scottish social event in June there was another which was the same. I did have black leather but swapped and really like it. I have the A6 armrest which is black. I thought about changing it to red but think it breaks it up a bit.
Thanks.
As BirtyA2 has mentioned, that's the oil separator. I'd changed mine few months ago, it was full of yellow gunk, oil+water mixture, due that, it was rather heavy as well. With undertray and car on ramps, it was not too difficult to change it, just make sure to unplug/remove the bits connected to the oil separator hose first, and one of the bolts sits higher, so you need the sqeeze your hand a bit. Also check/clean the rubber hose connected to it, as on mine that was full of the yellow gunk as well.
Ah I'm lucky enough to have the full monty, sport wheel handbrake gear knob gaiter and doorcards! I will try and make social event in 23
I have a grey and red gear gaiters which matches the red and grey headlining but I've not gotten round to doing something with it. I bought an A1 sline gear knob since it's got the A1 steering wheel.
