ENGINE MALFUCTION LIGHT!! AHHHHHHHHHH

Mollymoo · Jul 18, 2018

Where do I start, 2006 TD4 126,000 miles. Had it for 8 weeks. The engine malfunction light was coming on whenever you wanted more power and especially on the mway above 70.Read a pile of threads and got this work done,
Air Filter, Turbo filter, crank breather, oil & filter, EGR cleaned, Fuel system cleaned, fuel filter, low pressure fuel pump. Done by a garage that only found an overboost fault before doing this lot.
Goes like a train until, yup you guessed it, over 80mph up a hill that light comes back on and power goes until I ease off.
What else could cause this?
HELP!

You can begin by taking your postcode off your profile

Done. See new boy to this. Doesn't help the problem though

Stick to 70 !!

I think it needs the proper landrover code reader plugging in to read the fault.

I know what you mean.
I had a Kia that had the engine management light on for the 4 years I owned it. I only worried about it when one day it started to flash, even then I only worried for about ten seconds. You'll find after a few weeks, you'll hardly notice it.

I don't worry too much about stuff like that either. If they start up, I will drive them.

But I think I remember reading that EML staying on is now an MOT failure.

It is.

Good job I got rid of the Kia then

Ideally you need to look at the for the low pressure and high pressure fuel rails, while the fault is happening.

Bloody hard at motorway speeds.

You get a willing helper to monitor the live data from the fuel rails and maybe the boost pressure too. Whilst you do the driving.

Never used on a land rover (have a series), but I bought a blue tooth engine management plug in thing and downloaded a reader app to my phone, the whole lot cost me less than £15 and I've read and reset codes on a VW Amorok, SAAB 93, Vauxhall zafira, honda crv, with no problems. Really useful as most problems seem to be just exhaust sensors playing up. (won't read airbags or any other safety system). If nothing else it will give you an idea where to start. Plus on the VW my app gave me more information that the super expensive one the garage had

What was the blue tooth thing called/made by?

Yang Wong Dongle, made by Mr Wong.

Or indeed any combination of Chinese sounding names, or Chinese variants of Engrish names.

Sold on Ali for £5 to an actual Engrish man, then on eBay to you for £15.

There are lots of cheap ODBII bluetooth dongles available.

I bought one, works a treat on every car I plugged it into, except my Freelander (in fairness, as expected) - but mines way older than yours, will work a treat on a 2006.

Pumpkin OBD2 Scanner, WIFI Car Diagnostic Tool Fault Code Reader Wireless Adaptor Auto Check Engine Light Clear ELM327 (from amazon)
with
car scanner pro app (as I have a windows mobile)
researched for ages to find one that would work with a windows phone and this one fitted the bill and well worth paying a couple of quid to get the pro version of car scanner

(make sure you get the right one, as reading the reviews you need the wifi one for IOS, BUT the blue tooth works great with windows phones)

Yeah, I got a cheap Bluetooth ELM 327, run it with torque app on my phone and tablet, and it works a treat. Diagnosed our lass's Nissan crank sensor bust, and summat else, and my lads Fiat, summat or other ... Very interesting live reads from before and after I serviced the Nissan, just filters, plugs, oils and a clean and tidy up of sensors and stuff. Every reading, and the graphs afterwards, from the 'before' were all slightly down from the readings afterwards! Pleased me no end to prove keeping things in fettle is far more cost effective (read that as cheaper) in the long run than just running 'em into the ground and waiting for 'em to go bang!

Check the boost pressure sensor (MAP sensor) on the left of the inlet manifold as you look from the front. First sign of it giving up is a loss of power at high speed.
Also, slow down you daft git.

+1 for the elm327 bluetooth and torque pro setup, cost me around £10 in total and has paid for itself many times over already. Besides my son likes to connect his tablet to it and pretend we are in fast and furious - not sure how that works though, I am yet to see the one where they drive either an astra diesel estate or a 2006 freelander td4 haha.
