Problems with 2007 Golf VW petrol engine: smoke, loss of power and other symptoms

Hi, you guys are really great! I'm so grateful for all your advice and experience. Thanks to you, I finally dared to make the annoying trip to the mechanic and it was worth it. Everything went smoothly! I described my symptoms with the injection restrictions as you suggested. And voila! That was exactly the diagnosis. Ignition coils, injectors and spark plugs were replaced, just like yours. Our mechanic was even able to keep the repair costs lower than expected, at only €1500! I am over the moon and my Golf is running like a charm again! Your help was immeasurable and your stories really gave me the confidence I needed to get the car fixed. Now everything is good again! Take care and see you next time! Stay safe and healthy! Best regards!

Hi, I recently had a similar problem with my 2010 VW Passat. The engine was running rough, it was stuttering a bit and had some power loss. It turned out that the throttle valve needed cleaning and a couple of spark plugs needed replacing. On a positive note, your problem doesn't seem to be too bad. It sounds like the ignition coils and injectors may need replacing. White smoke indicates unburned fuel coming out of the exhaust, which could be a sign of an ignition or fuel supply problem. Don't worry, this should be an easy fix from your mechanic. Give it a try and let me know how it goes. Good luck!

Hi, thanks for the tip! That sounds like something I could suggest to my mechanic. Your story with the Passat has shed some light on the whole thing. I was originally a bit worried, but now I'm a bit more confident. I do have one more question though, if you could help me further: can you remember roughly how much it all cost? And have there been any similar problems since the repair? Thanks and best regards!

Hello, I had almost the same problem. After the mechanic had a look at the car, the functional restriction of the injection was fixed and did not come back, fortunately. Regarding the costs, I spent around €600 on repairing the sensor defect. I have to say, all cars have their quirks, including my little runabout. I drive a BMW on a voluntary basis. And as you know, the older the car, the more likely it is to have new problems. But that's the way it is, isn't it? Take care and hope this helps you! Best regards!

Hello, I also experienced something similar with my Audi some time ago. The signs really look as if the functional restriction of the fuel injection is the cause. Your Golf has already clocked up an impressive mileage of over 200,000 km, so such problems can occur. As far as the exhaust smell and poor fuel consumption are concerned, it could be that your petrol engine is not burning properly and therefore the performance is diminishing. The black smoke can also be a sign of this. Repair costs can of course vary depending on the amount of work required and your mechanic's prices. In my case, the cost to fix the problem and fully restore the vehicle's condition was quite high, but it was definitely worth it. I would recommend you make an appointment with the mechanic as soon as possible to have the problem assessed. Of course, the longer you wait, the greater the chance of it getting worse. Good luck and have a safe journey! Good luck!
