Do you have problems with your car? The engine does not start? Is it jerking? He oils. You don't know what to do next? No problem! Auto Pope Andreas Kessler will help you. Today it's about a Volvo.

Question from Stefan:

Good evening, I have a problem with my 1998 Volvo V40 station wagon. It smokes white from the exhaust. What could that be? He also runs into the emergency program. Thank you in advance for your answer. Best

regards, Stefan Autopapst Andreas Kessler answers:

When the car mutates into a fog thrower, it's either very cold outside (in winter !!) or the car has a cylinder head problem (crack in the head or a defective cylinder head gasket). Both are expensive to repair and usually not worthwhile for "used cars". Cheers from the auto pope

Question from Lydia Strauss:

Dear Mr. Keßler, my papa advised me to write to the auto pope because you made the correct diagnosis with his Frontera back then. My Opel Astra Caravan (type AH / SW, built in 2004, displacement 1598cm³) suddenly rattles in the engine area. The rattling can be heard when the engine is started; the rattling increases with increasing engine speed. My father said the car sounds like a diesel, but it's a gasoline engine. An oil change in the workshop did not help, now they think there is an engine failure. Would that also be your guess or do you have another tip? Many thanks in advance for expert advice, Lydia Strauss

Autopape Andreas Kessler answers:

Hello Lydia, it is definitely an engine failure, because something in the engine is making this rattling noise…. But: Maybe it can be repaired! To check what it is, I would take a look under the valve cover and check the condition of the camshafts! When they are run in, the sound described is exactly what is produced. Replacing both camshafts is not cheap, but it may be cheaper than another car….. Good luck with solving the problem, The car pope

Question from Lars Sielisch:

Hello Mr. Kessler, I drive an Audi A42.0 petrol engine with 130 PS from 2002, engine code. "OLD", switch. The car was equipped with a Vialle LPG system in 2013; then the car had about 120,000 km, now it's almost 223,000 km. For about nine months I have had more and more serious problems because the car goes out at traffic lights, in a traffic jam, etc. Fortunately, it usually starts up again quickly. It started at the end of 2016 when the Audi started poorly, especially when it was "half warm". The camshaft sensor, spark plugs (especially for LPG operation), speed sensor were renewed, all without a noticeable effect. The conversion company Autogas Hager Berlin first had the car for troubleshooting, unfortunately without success. After that, the Audi was at four different independent workshops, and nobody was able to pinpoint the problem. You are my last hope now. Thanks for your effort. Kind regards Lars Sielisch

Car pope Andreas Kessler answers:

Dear Lars, in order to be able to assess the problem better, I still need answers to the following questions: What are the compression values of the engine? Do you drive with valve control (Flash-Lube)? Do the problems also occur when using petrol? The bottom line is that I think there is wear in the cylinder head rather than a problem with the gas system. Unfortunately, troubleshooting and a good diagnosis are time-consuming and therefore expensive. Please pull the rip cord in good time, another, non-defective used car is sometimes cheaper than endless repairs…. Cheers from the auto pope

Question from Maxim Rosenbauer:

Hello dear Auto Pope, I hope you can help me. We have a VW Multivan DPF Highline automatic. Sometimes it doesn't start immediately, but it always works after a maximum of one minute. The biggest problem is that every now and then when the journey is slow (happens from about 1 hour driving around) it starts to shake and then goes out. Then it takes another 30-60 seconds for it to start again. VW refers to the intake manifold flap. We've already had the bus repaired seven times, but nobody knows what could be the cause. He's been to VW too. The bus has already traveled 230,000 kilometers. Should we rather repel him or is there still hope? We are a small company from Berlin and it is with a heavy heart that we want to part with the car. Thanks in advance!! Maxim Rosenbauer

Car pope Andreas Kessler answers:

Dear Maxim, a T5 is an extremely complex product. The highline models in particular are, once defective, almost undiagnosed for most mechatronics engineers. If no entry is found in the car's error memory even when a good VW mechatronics technician with a VW diagnostic computer is questioned, an error log must be created during use. To do this, a DATA logger is plugged into the OBD socket, which records all problems so that they can be read out and analyzed later. A competent contact person is also recommended for this. Of course, the longer it takes, the longer it can be expensive. So you should set yourself a cost limit. Finally: I guess falling pressure in the rail of the injection … I keep my fingers crossed! Cheers AK

Question from Frank Oelschläger:

Hello, Mr. Kessler! Are all VW Golf 1.4 TSI affected by the timing chain skipping problem? Is it possible to narrow down such as year of construction or mileage? Many Thanks!

Car pope Andreas Kessler replies:

Dear Mr. Oelschleger, all TSI engines are not affected, but very many. For some it started at 35,000 km, others drove over 100,000 km without symptoms. At some point VW changed suppliers and made design changes. After that the problems were almost gone. When that was exactly depends on the engine type. VW does not disclose exact dates … Greetings from the car pope

Question from Anja Achhammer:

Hello Mr. Keßler, my VW Golf IV Longlife 1.6i automatic, 102 PS, EZ 03/2001, 140,000 km, has been using more and more engine oil since 2011. At the end of 2014, my home and yard workshop switched to normal oil, which initially lasted almost 4000 km. Since then approx. 1 l / 1000 km, most recently approx. 600 - 800 km. The engine was then taken apart by a specialist engine technology workshop and all the gaskets that existed were replaced. Only the piston rings were not exchanged and supposedly looked good. After the repair, there were enormous misfires and after 1500 km he wanted oil again, now there were really nice clouds of smoke. In the meantime an ATM with approx. 50,000 km has been installed, but the misfires stayed and crankshaft and camshaft sensors triggered error messages. Now they are of the opinion that the engine control unit is defective and sent it to a competent company for repair. Could a defective engine control unit have been the cause of the increased oil consumption before the engine was changed? I have had error messages of all kinds for a long time, mostly mixture too lean. There were also misfires from time to time. Many thanks and best regards Anja Achhammer

Car pope Andreas Kessler answers:

Hello Anja, very briefly: The old engine was through, the cause was most likely the piston rings. They cannot be checked by quickly looking at them, an engine manufacturer could judge more competently. The current problems cannot be solved by remote diagnosis, but the ignition coils are very often the cause. Unfortunately, there are always many "construction sites" after an engine replacement that can cause trouble. Has the toothed belt been replaced on the "new" motor? If so, be sure to check the timing again. The workshop man is in demand here…. Cheers AK

Question from Katja Proksch:

Good evening, I have the following problem with my Daewoo Nubira. 1.6 liter gasoline engine and built in 2000. It was now in the workshop. Started poorly and jerked while driving. You have changed the spark plugs, ignition coil and ignition cable. In the cold state it is a little difficult to walk, but it starts. As soon as you have driven a little, also, only on short distances it stutters and does not start anymore. What could that be? Mileage is now around 183,000. Do I now have the option of repairing the workshop, since the problem was not repaired?

Car pope Andreas Kessler answers:

There will be no warranty here because the work carried out was carried out free of defects. You haven't eliminated the cause of the "discomfort", but you haven't made the problem worse. It could have worked … The crux of such problems is actually the diagnosis: If you want to find the cause with certainty, you sometimes have to look for a long time. This is expensive, which is why many workshops work with standard solutions with a high hit rate. Sometimes the shot goes wrong, then you have to keep searching and paying. Especially "Ausgeher" and "Stuckler" don't really want a workshop man because he doesn't want to search forever. So: Asking nicely whether you can not check again after all is always possible,There is no entitlement to free repairs from the previous day. The auto pope wishes good luck
