At 1:04 - you see the metal clip, that holds the thermostat together. if you remove it it splits in two and you can remove the actual metal thermostat tube inside. This is the part that goes wrong. It means that you can fix this problem by simply splitting the thermostat on the vehicle then swapping out the internal part without removing any pipes. Much quicker!
when it's cold outside, it doesn't reach the working temperature of 90 degrees, it's 50-60. If I drive it more aggressively, it reaches it, but when I drive it at lower revs, it returns more slowly. I replaced the main thermostat and this small one with a CEI one twice, and it's the same five times. .Audi Q5 2.0 tdi 105 KW 2012 CJCA Motor Can the non-return valve cause a problem and does this engine have one and what is its function. Thank you...
Having the same problem with my 2.0tdi in winter I leave it running 20minuts before driving of as it takes that long to get over 50 and then if I drive slow or downhill it just stays cold only Tim I reach 90 is on motorways or in summer
Hi! Probably a silly question, Is it possible to remove that part without draining coolant first? I see it quite at he top of the engine so... just asking to be prepared when I change mine. Thanks a lot!
Dave have u the part number for this . I can see it down the back of the engine on my 2010 seat exeo 2.0 tdi cag engine but not sure if it's just a joining piece or a thermostat . Thing is a night mare to warm up in winter
You have tools I have never even seen before Dave. I take it the cable actuated tools are for confined space use. Essentially allowing you to remotely operate the handles ?
Hey ian. Oh aye these are for inaccessible clips. They are a must on cars nowadays where there is limited space. The red one has a ratchet which holds the clip open. The blue, ive disabled the ratchet so i can control the opening. I thought they would be commonly used. Maybe not so across the pond. Take care, dave
Common problem not resolved by changing the stats as I have. My CJCA engine in my Exeo doesn't lift off 50°C for at least five miles in winter or below 5°C outside temp. You need to give them a blast down a fast A road evey now and then (ecu regen mode if your aware of it) or you'll get a blocked dpf. READ EXPENSIVE!
I just brought an A4 Tdi e 2012 CJCB - believe it might be the facelift model a few months ago never sits at 90 degrees . noticed the tempreture on a 2x 200 mile non stop motorway journeys the tempreture at most hit 70-80 degrees. Even in standing traffic will not hit 90. My engine has no oil dipstick either . I assume this is a similar engine to this . Should I try changing this valve first ? Or the actual water thermostat ?
Hello Dave, , My Audi A4 2014, Warms up to 90 and keeps at 90 degrees while driving, If I am stuck in traffic the temperature starts to drop. after 40 mins it will be back to cold ! I was thinking the thermostats is stuck partially open and was going to change it. How can i know if it is the main thermostat or the inline thermostat you changed in this Video ? thanks a million!
Hello dave, Thank you very much for your explanation. Do you know if it's the same thermostat reference for 2.0 TDI Caga (audi A5 2011 143 automatic transmission) Thank you in advance
Iv changed my main thermostat and it actually reaches temp now But as soon as i put my heaters on it drops to around 50/70 Will this inline stat help with that?
Hi Dave thanks for info in video, I’ve got a seat exeo 2.0tdi 2012 143hp . It says this part doesn’t match my car, do you know if it will fit or the correct thermostat part number for my car as I can’t seem to find one anywhere? Cheers
Hello my problem is in Audi A4 B8!in morning it cant reach 90°C temp if its below 0!But when finish work at 15 its normal temperature 90°!Is that thermostat?
yes it made a difference. However, if the ambient temp is below 5 degrees centigrade, the coolant temp needle will fluctuate on TDI's. This is normal (info from an Audi bulletin)
Dave do you know if this engine have check valve(non-return valve - looks the same as this thermostat) in hose? I know this is located in same hose on the B8 but not sure if exist in the B8.5( facelifted models).
Yes, it does exist in facelift but it is integrated in angled hose itself, you can feel it in your hand when you try to bend hose. It is really bad quality and gets bad at around 60k km
@@7kunac486 i know that part, is a metal pipe that comes with rubber hose on both ends. I assume the valve will be on the side with the slightly longer rubber hose
@@davesterl So have you fix the issue by changing this ? For me is quite normal in low ambient temperatures for the coolant temperature to drop if you are descending a hill in gear and you have the heating on. Basically, your are extracting more heat from the coolant than putting in as the engine does not inject any fuel when you engine break.
dave sterl yes Dave I’m from New Zealand and I just bought a same Audi and I have the same issue. I have asked my Audi dealership here and they don’t know anything about this thermostat. They only have one main thermostat listing
I will try to be as short as possible, but it is simply impossible on this topic. So: This is a major drawback of usually 2.0 tdi engines from 2005. and further on, the most pronounced at Audi, and less at others from the group. The theme of all Audi groups in the region and Europe, even America. Forums, RU-vid channels, etc. Working temp. in colder weather it doesn't hold 90C, it walks and spins mostly around 50C or lower depending on driving style, outside temp. etc. Working temp. is generally achieved only at higher speeds and most engine revolutions. Heating is usually almost normal in the vehicle if you have additional electricity. heater, and if not, then it is also weaker. In warmer weather, usually at +10 or more C outside temp. everything is normal without any indication of problem. Given that there are several engine models according to the markings, there are also several models of the cooling system installation itself, and usually they are a few very similar variants. In general, the problem is generally hidden in a few parts, namely: Main thermostat, small hose thermostat. and non-return valve (the last two can be located at the joint of the rubber hoses and in the hose itself and in most cases it is next to them.) Depending on the engine mark, type of gearbox, vehicle model, engine power, market for which it was made, purpose and who knows what else there are so many of them built into each system and so many individual coolant circuits in the system. We also have additional el. water pumps, but they rarely cause problems. There are many schemes, displays, etc. but the only reliable method of finding them is a detailed check of the rubber hoses, with which we can very easily determine how much there is. There are mainly two models of non-return valves, one that goes into the hose itself and is visually hidden, and the other is also hose and is similar to m. term. and is visible visually. Automatics usually have another small term. in my case on the vehicle Audi Q5 2.0 tdi 105KW manual transmission Engine CJCA: 1 main thermostat, 1 small thermostat, 2 non-return valves
