The method is not fool proof, its impossible to drill a hole through the top without damaging the blue electric tape inside, because you cant see where to drill the hole. The picture you just posted, I have seen on the internet before, it clearly shows that the top plastic part has been cut all the way around and the hole is drilled rather from the inside. The throttle cable and black plastic cover dont need to be removed, providing you place a towel on the base of block, to protect the air filter cover from being scratched. In fact I did libererally spray a fluid down the center spring section and guess what! nothing happened, it stayed in there and did not work its way down, infact I had to pour it back out, so there is no possible way the fluid makes its way through that section. If you want to post a picture of your sensor, I expect to see your smiley face against it as i doubt that the picture posted is of your sensor. I hope anybody with the same issue, does NOT attempt any of this, as it is fruitless.
There is no blue electric tape inside, those copper tracks are on a solid blue PCB. If you've seen that picture before then you will have found out who posted it and how he and others fixed the APP sensor .
You probably did get fluid down into the tracks, but you need to keep it in there for a while and rotate the mechanism back and forth. And yes I did remove the assembly from my car, I don't need to prove it to you, I did it to be sure that your DIY is cack-handed.
?? All 4 x 10mm bolts were removed, it was never bolted to the bulk head. This part is not a repairable part. Any attempt to do so remains fruitless. Despite the relentless effort being made to convince me otherwise there is Not a shred of evidence to support this from any member on here so far who has actually removed it cleaned it and fixed it. None what so ever.
Why would we make this up ?
Why would we waste our time typing out information to you to try to help you ?
Why would I go to the trouble of removing the one from my own car to check how simple it all is ?
I am a Chartered Electronics Engineer, I started off as a hobbyist on valve radios and TV's over 40 years ago, and I have a Bachelors and a Masters in Electronics. Up until 20 years ago I worked in various industries as an Electronics Design Engineer (including automotive test beds), after which I moved into Mobile Phone Networks as a Radio Planning Engineer.
I don't appreciate someone calling me a liar, or implying that I am complicit in some gang giving out bad advice.
You now have several choices, listed in descending order of cost
1. take your car to a dealer to get the work done
2. take your car to an independent to get the work done
3. buy a new APP assembly and fit it yourself
4. buy a new sensor from that link on ebay.com (which was not originally provided by me)
5. buy a 2nd hand assembly from a breakers (but you don't know how long it will be before that starts to throw APP codes)
6. continue to put switch cleaner into the one that you have
7. leave it alone and continue to use the cruise control when driving
The choice is yours, but if the APP starts throwing codes on the CM2 in my possession, I certainly would not bother with the first 5 or the last 1 in that list.
