Iveco Daily often have the immobiliser system go down resulting in no start or intermittent start & a code / key icon warning lamp flashing in the dash.. .Vantuner can delete / bypass the factory immobiliser completely by simply reprogramming the engine ECU at a fraction of the cost of any alternative.. Models covered all & any 2.8/2.3/3.0 from about 2002 up to about 2011 & even some later ones. When the immobiliser is working OK, the code lamp, with its key icon, will light for 3 seconds then go off. You will hear the fuel primer / lift pump wiring for 4 seconds each time you turn the ignition on. Checking there is voltage to the primer/lift pump is a good idea to help establish the actual fault. There is a fuse & a relay that feeds this circuit ( will add detailed info later )
The engine ECU must be removed & posted in, once you get it back , disconnect the immobiliser box (pre ’07’s) , reinstall the engine ECU & you’re good to go. The immobiliser’s / key code lmap in the dash should now be off ( if Euro 2 or 3 type ) & the van will start. Usual turnaround is 1 to 2 days or you can book in for it to be done while you wait if you bring it here by car etc. Euro 4 onwards will still have the immo lamp lit.
The ECU on RHD vehicles , is located under bonnet, on the right hand side , further right than the battery so remove the battery to get access, & remove any bracketry prior to posting. Its easy to short connections on these van’s so one tip is to remove the positive terminal cable from the battery & put it straight into to a glove or 2 then stuff it out of the way.
The postal remaps page here has details of where to send & how to pay etc, & don’t be shy about posting it, the units are shockproof & I’ve never lost one in 8 years of doing this via Royal Mail Special Delivery – You can just use a size H Jiffy bag on all but the earliest type in the 1st picture & a small section of cardboard to protect the connector end.
You’ll find your engine ECU is made by Bosch & has one of the following part numbers :
0281001537, 0281011228, 0281012193 – all of these can have the immobiliser deleted /bypassed.
Here is the earliest type ( 0251001537)
Here is the one that most commonly fitted to vans that get problems – part number 0281011228, the Euro 4 van’s with ECU part number 0281012193, have an almost identical look.
Below is the immobiliser box you have to permanently disconnect if your van is a Euro 2 or 3 , (produced from roughly 2002-2006)., The box, if fitted, is located just forward of the steering column , under the dash, Its tricky to see & even harder to remove but you can unplug its two plugs in situ or undo the 2 Torx bolts holding it in & you ‘ll then find unplugging much easier.You can locate the immo box by tracing the wiring down from the receiver ring that surrounds the ignition barrel.
This is a picture of the ignition & key, receiver ring that picks up a signal from the key, & wiring to the immobiliser box, to give an idea of the offending systems components size & look.
Whilst the ECU is here , speed limiter removal or tuning for economy / power , torque can also be carried out.
