Back from the garage. 

Ruled out the EGR cooler after that was pressure tested. Ruled out the heater matrix 

Been told to monitor how much I’m loosing at take back in a couple of weeks. 
 

Whats the next logical thing that should be tested/checked? 

So after the UV dye test i can’t see anything around the engine bay. But there is couple of drops showing in the oil when I take the cap off. Still a slow leak and I’ve probably lost a couple litres in total the oil isn’t milky or grey so it’s not all in there 

Been into the garage. Didnt drop under pressure again. They’ve checked common areas including the water pump. Nothing visible. After a road test more leaking. They’ve put dye in the system and told me to go back in a week. 
 

After a little more research I’m starting to think ERG cooler as it’s not always obvious and can still hold under pressure. What would be the best way of testing this? 

Been in to the garage and all these faults were caused by a faulty ABS sensor at the rear it was given false readings compared to the rest 

Battery voltage is 12.6v with engine off and 14.2 with engine on. No blown fuses either. 
 

It'll be in the garage Thursday so we’ll find out what’s the crack 

I believe we tested it at 26 psi for about 20 minutes. Serviced every year by previous owner. I had the timing and water pump done at 75k I’m currently on 105k. No other engine related in the two years I’ve had it. 

No moisture inside the cabin. I’ve lost probably 2 litres since the issue has started about 3 weeks ago. I have a feeling it’s either evaporating or being burnt up. Would that much loss being burnt in combustion have a noticeable effect on performance? 

Here’s a list of trouble codes I’d that helps 

03841 - RPM Sensor Rear Left: Incorrect Signal.

00290 - ABS Wheel Speed Sensor Rear Left (G46)

01316 - ABS Control Module

Tried a new cap straight from Audi

So I’ve got a slow coolant leak. Maybe topping up the reservoir an inch or so every 100 miles. Only seems to leak on longer journeys. 
Can’t see any signs of leakage no puddles or wet patches nor any pink corroded areas. Pressure test seems to hold pressure. No sign of coolant in oil, exhaust smell in coolant tank or white smoke from exhaust. 

What areas should I check next? What’s all the possible areas that coolant could leak internally? 

Car is a3 8p 2.0 170 TDI CFGB engine 

Many thanks in advance

It was just a photo of the battery. Looks like like the terminals have crusted over a bit. Alternator seems to be fine. I’ll get it to my local mechanic in the new few days

Mr Halfords says my batteries at 99% health

I’d hope not it’s only a year old and supplied by my local Audi specialist. But thanks Ill do that first thing in the morning 

Hello, friday morning I has these errors all come on at the same time whilst starting up. I just wanted to check if they're all likely to be related to each other/a fault with the ABS sensor? 

Ive seen a few posts about the ABS and stop start being related but i dont see how the headlight range control could be? 

It looks like a pretty cheap/easy part to replace if thats what is causing the issues. Or is there anything else i should check first?  

Many thanks in advance 

Im looking for the paint code for these wheels. Not sure if the paint code was on the sticker in the boot but it’s unreadable anyways. Car is a A3 black edition reg DS11OMY if that helps. Many thanks 

Any recommendations on a specialist in the Oxfordshire/Berkshire areas. I’m due a cambelt & waterpump and been quoted both £745 and £816 from two local main dealers 😳 many thanks
