I think the best advice I can give is to take your car to a good shop. You really need someone that has the corect equipment to do the job.
Could the Throttle Valve errors (1637 & 1638) im having, be due to carbon build up in the valves or the intake manifold?
Sure, the throttle body is in the same line as the intake valves. If the intake ports are blocked by carbon they won't flow as much air and neither will the throttle body, because the intake ports and the throttle body are on either end of the same pipe. If you step on the throttle, the throttle plate will move to a calculated position the Engine Control Unit expects a certain amount of air flow but it doesn't see that and blames the throttle body and so it set a code, P-1637.
Genik stop being a cheap ass and take your car to the dealership and let them carbon blast it already. You have this thread going and your other thread all about the same thing CARBON! Stop posting and start spending some money already.
Internet to Genik: "Please turn left. " Genik to Internet: " so if I turn right that will be better correct?" We are the fun community here, but this is starting to get a little old. We asked where you are located and you act offended. We are not going to invite ourselves over to your house, but we may know a good place where you can take your car. Your near Atlanta, we know a guy. Detroit, we know a guy, Southern California, we know a guy. Get the picture? Tanzania, nope don't know a guy. Sorry . To be honest your lack of cooperation is the type of behavior that turns people away from wanting to help you. I get it that you don't trust paid techs and dealers, but a MINI dealer will have a procedure process for your errors with exactly what to test in what order to isolate the problem. There may be numerous individual pieces that could be the root cause. This is not throwing a part at something and hoping the problem goes away. It is a methodical test plan. Do you have a Bentley manual? If not, this is the next step for you. Order one and start reading. It is the single source for maintenance on a MINI. Carbon buildup is not the answer to all questions.
This is a sad scenario. All the help that has been offered, by so many caring folks, and not even so much as a hint of gratitude. You guys rock!
Not a shot in the Dark at all, this is true. Your miles away from others DneprDave, thanx for not thinking the obvious (most people judge by thinking the obvious).
No one is judging you. It's just this problem is not something you can fix. You don't appear to have the technical knowledge. We have been trying.. dneprDave told you No. But you changed the part after being told that was not it. Then you were told it may be carbon build up and asked how to check it DneprDave told you and you said you can not do that. Ok we understand but then you must take it to a thech. Read what you said in the above post. We say it may be carbon. You said all tech say the R56 has a carbon problem. But you keep asking if it's some other problem. Just because a car gives you a code does not mean it is that part. It could be but you need to make sure. You even started this thread saying you did not want to take it to a shop that just changes parts. But you are doing that. You changed the HPFP after being told that was not it. Two of us have explained how carbon may be your problem. But you still ask if it is something els. You have us and mechanics telling you to have it checked for carbon, but you will not do it. I can offer no more help. Before you do anything els to the car you must have it checked for carbon. I am not trying to be rude, I just want you to understand why some people are getting upset. We are trying to help but you are not listing. Good luck and let us know if it gets fixed.
I know you specifically and some others are not trying to be rude, but im gathering many opinions thats why i ask a lot. Unfortunately i've been disappointed by many techs (believe me you wouldn't want to be in my shoes) thats why since i'm taking decisions on my own i have to check and double check! Regarding the HPFP i believe i was right, so you cant say im just changing parts! Regarding the Throttle valve, techs straight away suggested on replacing it! By asking around (you guys too) led me to think that the Throttle valve might not be the issue, but it could be carbon. In a few days i will know for sure if those errors (P1637 and P1638) appeared due to carbon build up. If im right, it means that it was well worth asking around again and again, if im not, ok then guys, you can crucify me! :biggrin5:
can the timing be changed on the N14 engine to prevent the carbon build up as suggested here on this video? [ame="https://www.youtube.com/watch?v=IzXeeCiSL7k"]video[/ame]
IMHO, if the engine's tuning could be altered in such a way so as to eliminate the issue, it would have already been done. Not necessarily by MINI, but by the tuning experts throughout the MINI community... It's a design characteristic and is a very common occurrence. My buddy just went through this whole process with his 2007 R56S. A very frustrating time for him, which was ultimately corrected through carbon removal at a local shop, a new fuel pump and new timing chain. The latter repairs were performed at a Sacramento dealership. The results were a return of the car to normal horsepower and operability. Good luck as you pursue your solution.
MINI did change the timing on the newer N18 engines, they added VANOS to the exhaust, among other things, to reduce carbon build up on the intake valves. Unfortunately, There is not a lot you can do with the N14 engines other than cleaning the intake ports every 50 or 60 K miles.
Carbon buildup is nothing special to mini. It happens with all DI engines. Just take it to a dealer. VW/audi has issues with their 2.0 as well. I'm sure there's one of them around you. Just do it.
