What have you done to your car today?

So my issue was osf boost hose came away from intercooler. Partially installed hardpipe kit on that side. Seems better just got to do the other side now.
 
So we've been waiting for my gfs v5 for the past 2.5 weeks now.. got feed up and called the trader.. guess what, he hasn't even sent it out yet because he can't find our postcode!! Which is on v5!! And he couldn't be bothered contacting us? Absolute donut.
 
I got really annoyed because the dealer is dragging his feet booking me into a garage to fix the DTC on the MPS.

So I spent 2 hours on the issue myself because i wanted to get to know my engine bay. What better way to do so than ripping it apart?

I dismantled the entire Intake, intercooler, boost piping and MAF -> ECU wiring.

My findings:
- Boost pipes were not clamped down with much force.
- MAF Wires fine.
- MAF sensor mountings threaded... So MAF was actually loose.
- BoV pipe to intake hose was not clamped at all. Was so loose it fell out when I removed the BoV.
- Breather pipe to Intake pipe Oring perished.

I have lots of bits in my garage so managed to fix all the issues.

I then did the following:
- Refitted the Boost pipes and IC. Clamps on correctly.
- Used some Gorilla Glue down the MAF mounting holes. When set I refitted MAF sensor. Nice and secure now.
- Fitted Clamp to intake -> BoV pipe.
- replaced Oring with slightly thicker one on the breather pipe fitting.
- Fitted a banjo bolt to stop idle turbo seal seepage.

Results:
Idle seems to be hovering around 700-740 now. Still lumpy, possible misfire. - Might get some new plugs for it when I do a service in summer.
Less "wooosh" noise from the engine bay when accelerating.
No DTC Code from ECU after a 10 miles drive about. <- Most important thing.
Vacuum was 17 before and now its 20.4 on idle.

I will see if the error is now gone tomorrow after my 25mile trip to work. Hopefully, it was simply due to the intake clamp missing.

I have a feeling the previous owner removed an expensive intake prior to selling.
He then must have just stuck it all back together without giving a crap.

I also made a note of the "2015 turbo" that was supposedly fitted to this car... in actual fact, I very much doubt that it has ever had a new one in its life. The metal discolouration is the exact same as the rest of the engine metalwork. If it indeed did have a turbo less than 2 years ago then it would not.

Received my first NIP in the post after 13 years driving. 48 in a 40 just before a 50 zone. Bah. I saw the van at the time, but sun + fatigue = mistake made. Hands up, trousers down. Hopefully a course will be offered. Seems Lancashire constabulary offer it up 53mph in a 40.

Haha yes. I'm just impatient though and more than capable fixing it.

I am looking forward to finishing my uni essay so I can get the time next weekend to fit the entire suspension refresh :)

EDIT:

Drove 25Miles this morning.
No Error codes, or pending faults.
And... it averaged 38MPG on the trip which included traffic.
That's 11mpg more than before... so i think its fixed.

Audi tyre foam is utterly useless/worthless, can't find a tyre shop within 85 miles with the tyre I need :p

Got the MX5 back, no more rubbing and it handles like an absolute weapon, its ludicrous. The suspension is firm enough but still reasonably compliant. I was expecting it to feel like it had welded shocks because it is so low, but its OK. :)

Oil burning situation not as bad as previously thought. Seems to have drank about 400ML in 200 miles, which obviously isn't ideal but its manageable, and I'm hoping I can reduce that in the short term with this thicker high performance oil I've bought.
 
That is horrendous oil consumption. Using a bit is one thing but not being able to drive the thing for worrying how much it'll make disappear isn't sustainable.

Plan to sort it, sooner rather than later

Poor tyre :(

In other news.. Error came back.
Booked into a garage down the road first thing in the morning. Fed up now.

What issues are you getting? Symptoms etc?

Well my boost leak became apparent again. Turns out it was the screws which go into the MAP sensor housing on the hardpipe kit. I reused the old ones as the kit didn't supply new ones.

Found some in the garage which worked a treat. Also realised my hardpipe was resting against the sump. Cable ties and coat hanger later it's sorted.
