AC Condensor inspection / replacment

About 6 months ago my AC started blowing hot, sure sign I had a leak. During the refill the guy could hold pressure so was happy to recharge and this time add some yellow dye.

The AC system has just started to blow hot again, highlighting Iíve got a relatively small leak. Looking around with some UV light Iíve spotted My top suspect, the bottom left of the condensor (as you look into the grills), however it appears to be venting the yellow dye onto the main radiator, suggesting the dreaded F10 condensor part weakness rather than a rock impact.

My next task was remove the top brace and covers above the radiator and condensor to get a better view of the back side of the condensor.

Has anyone had this issue on their car and any tips / tricks to try / look at?
Not planning on taking a look until Friday so any advanced support would be ace.

I can't relate any direct experience on the F10, but if it helps your diagnosis confidence, I've read the condensers are weak in these cars. Your troubleshooting plan was solid. I would just find a TIS and follow the procedure for R&R condenser. If you have ISTA, it has TIS loaded too. I found this to be a great feature of the program and have started using it maybe more than the diagnosis capability.

Not to get totally sidetracked; for the removal, I would still have the shop do a pull down to remove the remaining freon. I know it's a pain to go there 2 more times (removal and then recharge later) but it's safer than putting that crap in the air you (we all) are breathing.

Good luck. Take pictures and post updates here!

i had two months of my warranty left and the condenser blew when it was 36C.
Bm changed it for no charge but wouldn't open up whether it was manuf. fault or stone hit.My guess is that it was too light a construction for weight saving.

I was on my last 3 months of warranty when my a/c failed. I was pretty certain it was the condensor issue, a weak spot on F10s and booked it into the dealer for a replacement.

They then refilled it and said it was holding a charge and blowing cold air, fair enough I thought. A week later it was blowing warm again, so a bit annoyed, I took it back to the dealer again and this time they agreed it was a faulty condensor and replaced it, all good since then.

I went through the same scenario back in Sept 2018 . I was really annoyed because I am in the HVAC field, so I know when a system has a leak. When I came back 2 days later I was NOT a happy camper, and they bent over backward to accommodate me since they did not listen to me the first time.
