Engine Warning Light, EGR code and Restricted Performance - Eeekkk!

Evening chaps.

OK so my woes go something like this...

I was driving the car the other day on a duel carriageway, minding my own business, 60mph when I look at the clocks and I see a red engine warning light, at least I think that's what it is.

Speedometer Vehicle Trip computer Odometer Gauge


I borrow my girlfriends dads OBD reader, plug it in and it gives me this code. In the booklet it says EGR faulty.

I managed to clear the code and the light went out. Result! Then the next day, driving down another duel carriageway, I go to overtake a car and as I am accelerating the car kicks down a gear and I hear a bang! Then I realise I have no power and on the dash it says Restricted Performance.

I managed to limp the car home, and today I called out AA. Guy turns up, starts the car and says, does it always sound throaty like that, I said no it doesn't, he opened the bonnet and we found this:

Simple pipe had popped off as the car kicked down. I asked about the error codes and he said they have been cleared and they were all relating to this.

I drove the car today, lovely, as I near home, damn engine light on the dash again... Fed up.

So clearly that pipe coming off wasn't the issue and maybe I do have a faulty / clogged EGR.

I did the, Entering Test Mode on the car, the gauge sweep thing and saw this information from onboard diagnostics:

ACC - FAULTY (true, the air con has stopped working)
HDM - Faulty (not sure what this stands for)
ICM - Faulty (again, not sure what this stands for)
TPMS - Faulty (I don't have a tyre pressure monitoring system on this car)
PATS - Missing (huh? lol)

DTC's

Soooo questions if I may?

What's wrong with my car 馃ズ

And where do we start ? I guess with the engine management light on.

Q1. The OBD reader thing I gave back so I should really invest in my own. Is there one that works well with the Jag or will any do?
Q2. If that OBD reader was right and the EGR is at fault then what are my options with it?

Firstly where is it, secondly can it be cleaned? And is this an easy job and will it require a certain solution? Can I use blanking plates and blank off the EGR to save this trouble? I did that in a Focus and it made a real positive difference.

I guess I'll start with that unless anyone else can spot anything from the DTC's or info on here.

OBD reader I think needs to be my first port of call. Do some give more info than others? Or can I shop for any, and any tips on the EGR side of things and what my options are moving forward I'd be super grateful for.

Thanks in advance :)

I am not sure why you are going ahead with this dubious procedure - most of the error codes were down to the pipe blowing off, the rest almost certainly due to low battery voltage.

With that knowledge, I would NOT be going ahead with the CAT/EGR/DPF delete nonsense. Especially not from an outfit that seems be using scare tactics about oil dilution on a car that doesn't suffer from it.

Summary - get the battery sorted and see what happens first.

If I were you, I would not tighten up the clamp On the pipe that came off. If boost pressure is high enough to take that off, your have been lucky that like many of us your intake manifold or intercooler didn鈥檛 blow off. Ignore all the battery related errors and check your MAF and MAP readings.

Hey guys. Some really useful information here, soooo please, thanks a lot.

So yesterday I had the Jag on charge all night long, 22hrs in fact. I took the car back to Fittapart and had a free battery check and this is how the battery is performing today?



The chap said give it another 24hrs and bring it back and he will give me another free test and he said lets see if we can get the state of charge to 100%.

So I don't know why the battery didn't charge to 100% after a 22hr charge, nor does it explain why the battery got as low as 58% charge the day after a 40 mile drive.

But anyway he said the battery is good, as is the alternator and the battery doesn't need replacing.

So we've at least eliminated the batt and alternator now which is good.
