I recently got a 2.0 petrol A4 avant with 127000 on the clock. The cambelt snapped in July last year and since then has done 5000 miles.
When I got the car a couple of weeks ago I noticed the coolant was below minimum (no warning light on but was probably 1.5 to 2 cm below min) and the oil seemed low too. I just checked the oil as the garage said they'd topped it up and noticed a small amount of 'mayonnaise' on the end of the dip stick after i wiped it first then put it back in (ie it wasn't there the first time I removed it, it was there the second time). I wiped it off and rechecked a couple more times and no mayo was visible.
Having just traded in my MG ZS for the Audi due to the head gasket going twice am I just paranoid or could it be going on the Audi? Obviously when the cambelt snapped the head was replaced. The oil filler cap is clear as is the header tank.
Please tell me I have nothing to worry about, I can't be doing with the stress of worrying about head gasket failure again!
