150km
Car remapped along with disabling the EGR (electronically). I replaced the oil breather with a vortex, and installed swirl flap blanking plates. Did approx 150 miles, then blew a tyre at slow speeds. Car sat idle for a week whilst I replaced all four wheels. Since, had a loss of boost/power to the point that the car struggles to climb hills below 3500RPM, and cannot get to motorway speeds. Only power is a tight, weak band at 3500-4100 rpm. Probably happened over about 20 miles total.
Turbo spools, but it does not sound normal. MAF and MAP both cleaned, no difference. Some of the vacuum hoses (at least the one going to the EGR) are old and frayed. I can't see the hoses entering the turbo. Engine produces no black smoke, maybe a cough of white when cold and first started but nothing after.
INPA Coding "4530 (1297) Air Charge Control".
Took it to local indy. "Turbo needs replacing as there is too much play in the shaft and so the bearings are shot and it's full of oil along with the feeder pipes and intercooler, also the egr is full of crud. Also vacuum hoses need replacing but they probably aren't the problem."
Turbo may be worn (fine). But that shouldn't stop any boost. Air Charge control usually refers to a problem with the vacuum system or the variable vanes.
Thoughts?
