White "Lion" Cupra - DSG converted track car
Shoduchi:
Yeap! This Leon looks the business! Glad you could get the DSG sorted so quickly and that the car is running as it should! :drinking:

I got the wheels from Germany, you can try also VW Racing Poland.
The car is running ok, but it is pretty hard to keep my hands off the boost controller until the software update. :driver:
Unfortunately a new problem has come up. It seems that while driving the car on D, at low rpm, immediately after some spirited driving, the oil pressure red light is coming up and I have to stop. After 5 mins, I start the car and everything seems ok again. Oil level is fine.
I have the 1.8T pump which makes lower pressure than the 2.0T oil pump, but I didn't have this problem over the course of 1 year. My theory is that I never drove the car at such low rpm as now, while in D the DSG gearbox shifts at under 2000 rpm and maybe this causes the pump to do lower pressure than my 2.0T pressure sensor is expecting.
My mechanic told me that we'll first change the oil and filter and told me he'll check my oil pressure. I don't know how he will do that, I don't have a gauge, but he's assuring me that he can do it.
And I have to check the subframe bolts, I've heard a knock at lower speeds and I know that was unmounted to change the clutch. It never ends... :phew:

Can't wait to see the wheels fitted, they look brilliant :smiley:
What oil are you running? You could try a thicker grade to help with the lower pressure?
Your mechanic will likely connect a mechanical pressure gauge to the outlet on the oil filter housing :happy2:
Do you have the TyrolSport deadset fitted to the subframe? It sorts that problem once and for all!
No, it doesn't ever end! All cars are the same though. At least with these cars the prices are reasonable. If you were racing a 911, your bank account would die very quickly!!

You're a car master, I've spoken with the mechanic, that is exactly how he will control the oil pressure. :notworthy:
I think now I have Motul 300V Power 5W40. I have to check when I'll get home on Wednesday (here is the Orthodox Ester and It's a small holiday) what I have in my reserve. I believe I have 2 types, 6L Motul 300V Power 5W40 and 4L Motul 300V Competition 15W-50 (which is not enough because of the extra oil radiator, I believe I need a bit over 5L).
I don't know exactly what to use because 5W40 worked well until the DSG and If I keep the car in manual mode, always over 2000 rpms, everything seems ok. It might be that the oil gets thinner in time, I have about 6000km with it, some of them pretty hard ones. But my mechanic also suggested thicker oil and I could try 15W50 of which I only need 2 more litres.
You're right, It never ends. A problem which I thought I solved has reappeared, seems that the hpfp is faulty. I'm getting some mid rpms fuel cuts which are getting worse. Last time I've logged the hpfp I've seen numbers like 117-125 but this was not felt, now the cuts are obvious. I'm worried that I'll not get away without a new pump. :phew:
On the plus side the DSG is brilliant. Now, with the new clutch pack it is lightning fast and I love the sound. I can't wait to see how it looks on those wheels with slicks too. Not much time left until 22.04 and I need to solve everything whith whatever resources I have. :smiley:
pudding:
That is how I would do it :happy2:
They are very good oils :happy2: I always had good luck with this and it's reasonably priced - https://www.google.co.uk/url?sa=t&rct=j&q=&esrc=s&source=web&cd=2&cad=rja&uact=8&ved=0ahUKEwivh5evuqjaAhUMJMAKHYLxBQUQFghjMAE&url=https%3A%2F%2Fwww.opieoils.co.uk%2Fp-68898-fuchs-titan-race-pro-s-10w-50-ester-fully-synthetic-engine-oil.aspx&usg=AOvVaw0YQApCaUyPfbD4qOR9z7sq
So you have an external oil cooler? Maybe that could be causing a pressure drop? You could try bypassing it and see if the pressure comes back to normal?
I do wonder about these aftermarket HPFPs. I have a Loba pump, 3 years old now, and I also get really bad flat spots around 2000rpm. I haven't logged the rail pressure yet but maybe the aftermarket pumps just aren't as well made as OEM and don't last? Not sure!
Glad you like the DSG :smiley: I like it too, especially the latest version in the MK7.5 :laugh: I hate it in auto mode though, it's always trying to find top gear too soon and when you kick down it seems to take too long to find the right gear. If only there was a way to lock it to the paddles only!
Good luck with the problems mate, I'm sure you will sort them all out :happy2:
