Hello after some advice please,, as the title suggests im getting gunk build up in the reservoir, so after hours scaling this forum and the net ive boiled it down to oil cooler or head gaske.now i dont think its the gasket as the oil in the car has no white residue, the car runs fine starts first time and no loss of power. can i repalce the seals in the cooler or is it a new one. my car does lots of short cold runs which i no dont help,any thoughts will be much appreciated
Thanks Ross

If you do lots of short runs then that is almost certainly the cause :wink:
-
In other words its normal!

thanks for the replys,my car does loose a little oil and first thing in the morniung its quite bad and the warning comes up saying check coolant, also i have had some issues with the system the stat went and also a small crack on the temp sensor housing appeared,so would you still say normal?

I'm assuming your replaced the thermostat? What about the coolant temp sensor? That could well be the issue.
How much oil are we talking? Whats the mileage on the engine? It could be completely normal usage.

yea repaced the thermostat,sender and housing flushed and filled with coolant also serviced it about 2 months ago.the engines done about 100,000 with my missis using it mostly school runs work ect work being 3 miles away max,once the cars run for half hour the warnings stop happening
-
the oil was full when serviced and today its on min about 2 months

Hang on, is it gunk in the coolant reservoir?

I'd assumed oil filler cap, but re-reading it would appear that it might be :lipsrsealed:

Is the gunk in the coolant reservoir then? How old is the coolant?

yea in the coolant i changed it about 2 weeks ago with the thermostat,temp sender and sender housing, reading other posts i think it could be the oil cooler,im going to look at prices today
-
Did you put the same coolant in as you had before? I know if you mix long life coolant and normal stuff it can go cloudy and eventually cause a brownish sludge to form.

That'll take years, if its sludge in the water you have oil contamination..

thanks for your help going to change the cooler this afternoon got the part from the breakers £35 vw wanted £125+vat ill let you all no how it goes

I had same thing to be honest and it was head gasket
After a while I started to get a water leak where it was boiling out overflow
I did 29k with this problem and the hole time I had no obvious head gasket signs
