12/4/2023 0 Comments Bmw low coolant lightDue to the absence of a spare tire, the trunk space provided by run-flat tires has increased. Some reviewers have criticized the rear suspension bump steer for being excessively harsh.Īluminum hoods and suspension components, and a magnesium roof frame were used to reduce the Z4’s overall weight. The rear moratorium uses a multi-link design instead of the Z3’s semi-trailing design. The front suspension on the Z3 is a Macpherson strut. The Z4 has a larger and stiffer chassis than its predecessor, the Z3. From 2002 to 2008, the E85/E86 generation was manufactured. Of course I'd check for any obvious traces of leaks or oil contamination - but with none found, just give it some more time and not sweat about it to much.The BMW E85 (roadster) and BMW E86 (coupe) sports cars make up the first generation of the BMW Z4. The VW authorized SA said almost exactly what the OP reports about his BMW SA - and when I dug the matter a bit more, totally unconvinced by his "explanation" - it turned out on the UK Golf R forum that actually the mechanic was totally correct (even if unconvincing): the knowledgeable guys over there confirmed there is an insider VW bulletin explaining that when filling the 2.0 300 PS R's engine at the factory, they are never able to put the amount of coolant which the Golf 7R's specs say - due to some quirk in the cooling system design of those engines which causes creation of an "air pocket" somewhere inside it which will evacuate very slowly, and - after several low coolant alerts during the first 20k miles or so - it will finally get evacuated, after all, and the engine will not need any top-offs any more. Interestingly, while I didn't have to add any coolant to my M235i's engine (yet I'm at 35kkm) - I did with my Golf 7R (same age, even slightly less distance covered), twice! The Golf has been the first car in my 47 years of driving which needed this (well - apart perhaps from a couple of "car-like" machines manufactured back in the righteously gone, communist era in Poland, by the Polish state "car industry" of those dark days). He said that during routine service they always make sure to "top off" the engine coolant The light went away but I was worried about a possible leak somewhere so I called my BMW dealership and told the service rep who nonchalantly stated that this was normal for BMW turbo engines, but couldn't really explain to me why. Once BMW replaced that part under warranty it never needed another drop of coolant. It had the classic cracked overflow reservoir. We've had 6 BMWs and none have ever needed a top off of coolant except for our 2008 535XiT. My guess is that they have a shitload of overpriced BMW coolant which they need to move - and they've found a way to do it. Service advisor was unconcerned and they made me pay for the gallon of BMW coolant which cost several thousand dollars (O.K., that's a slight exaggeration, but it was expensive). I was a bit surprised because I had my Z4 for 5+ years, my 128i ragtop for almost 6 years and the X1 for 3 years and never had to add coolant. Only had 25K Kms (about 16K miles) on the clock. If they put in standard green Prestone or any OAT coolant (typically red or orange), you need to have the cooling system flushed and refilled with the correct coolant to avoid future corrosion, sediment or plugged radiator issues. I've never had to replace the engine coolant of any of my other cars (non-BMW) before and wanted to get other thoughts on this? Should I be worried about a potential leak somewhere?ĭo you know what coolant Midas used to top up with? It needs to be nitrite, amine and phosphate free. He said that during routine service they always make sure to "top off" the engine coolant, and that if the low coolant sign came up that I could "swing by to get the coolant topped off" The car is about 2.5 years old with 20k on the odometer. I watched the technician put about 2 quarts of coolant in the resevoir. I was worried about it and took it to a Midas just down the street from my home. So last night I was driving home from work when the "Low engine coolant" sign came up on the dash.when I started the car this morning the light immediately came back on.
