Cragh

Sorry for my absence, I’m having to care for an 86year old and could do without the car trouble at the same time. can’t even find a replacement car, with the current silly prices. ive got no slipping clutch just this damn rattle/knocking. It has progressed over 2024 from what I thought may be an exhaust sounding rattle when pulling away, but I can get the sound up into 3rd gear now if going up a slight incline. it doesn’t even exaggerate the problem if I give it the beans.

Thanks for the replies. Can I ask what the spring is attached to, as the noise doesn't sound like a spring. The rattle is verging on a knocking sound. It started out quite quiet at the start of the year, and would probably hear it in 1st and 2nd gear when accelerating. It is louder now and can sometimes hear it for a second or two in 3rd if going up a smallish incline. And if it was a spring gone, would I not hear it when hitting a bump? Someone mentioned drive shaft but is an expensive job to find it isn't that

yes mate

Audi A4 B8 Avant 2.0TDi 2010 Technik (122,000miles) At the start of the year I could hear a faint rattle when pulling away in first, and thinking it may be exhaust, as it does have that sort of sound, I checked that out to find that was ok. I let it go to see if the noise developed and if I could locate it, but have so far failed even though it's got louder. I've had a mate (Mot Tester) look at it 3 or 4 times on the ramps, but he can't fathom it out either. Driving over bumps doesn't make it sound, but if the noise is occurring at the time of hitting a bump, it does sound to rattle with the bump. It only lasts for a second or two when the engine is under load. Don't really want to sell it yet with the price of used vehicles at the moment, but the noise is bugging me, and at some point feel the car will come to a stop one day. I thought at first the noise was coming from the rear of the vehicle but at present I believe it to be more central

Thanks Gareth. I mentioned the other bits in case they may be linked in some way. I don’t think I’ve ever had the temperature up to 90 during the colder days, but yesterday seemed exceedingly low. Heating in the car itself was fine, and car has been faultless this morning going to work. (Not any distance that I can check hoses)

Thank you for the replies. My local garage found no error codes but maybe I should get him to plug it in again now this has happened. There’s been a couple of times in the last year it’s kind of sounded a bit rough, but put that down to the times it’s gone into re-gen mode. i kind of got it in my head today that a sensor may have picked up the thermostat wasn’t working properly, which then was sending out the wrong instructions to something else, which was creating a fault. Maybe time to replace it. Had the air con regassed the end of last summer, but had to take it back the day after as it failed to cool. The fella that did it then found the pump had stopped working, but it started up whilst he was still underneath the bonnet, and it seemed ok thereafter. I didnt seem to be using more fuel today

Hi Guys and Gals. Newbie here, so be gentle. Very little time on my hands as outside work I’m having to be a a carer for an elderly parent. If I had a sticky thermostat, how would it exceed the engine. I had a run out today (38 miles either way) and all was well, but when I started up to head for home, idling was a bit ropey. I should have looked at the rev counter as it felt as if it was idling lower than it should. A quick blast on the accelerator pedal seemed to sort it. Whilst driving home didn’t seem as smooth as normal. I have been putting it down to regen of the DPF getting noisier with age, but noticed the temperature gauge had hardly moved. Admittedly it was 3’C outside and I had the heater on 21’C audi a4 Avant 2.0tdi Technik 2011
