    Dear readers,
    For my TF I want to do some advanced SCU programming, fob learning, and reading of engine codes.
    For my audi I am using VCDS for that, for MG PSCAN seems to be the tool to have.

    So therefore I am looking for a second hand pscan unit, could not find it on ebay or our local Dutch Marktplaats, so perhaps someone on the t-bar has one to sell.
    New one is 180 euro, for a garage of course peanuts but for a DIY, and being Dutch, I am looking for a somewhat cheaper 2nd hand option.

    Thanks
    Kind regards
    Theo

  • It is a 2005 TF. I have removed the pektron SCU, no signs of damage to the PCB, also the relays look good. So I am going to send the unit to Paul technozen for diagnoses. In the meantime I would like to check the wiring harness, to see if the door lock wires indeed make contact with the pektron connector. I need a pektron connector pinout to do that. Looking at the test results it would surprise me if anything is broken in the wiring, but I want to rule out that part of the chain.
    My idea of making a clone is useless to create a plug and play solution, because the key fobs are paired to a particular scu and cannot be paired to 2 scu's.
    I would like to have a go at programming a pektron, therefore looking at a second hand pscan. I will put the request on the forum.

  • I tested the motor by means of putting a 12 volt pulse to the wires and both lock and unlock works in that way.

    I put in a brand new duracell 2032 in the fob, but no luck.

    When I manually lock the doors I can unlock it with the fob.
    Locking with the fobs used to lock the doors, and the alarm led started flashing rapidly, and after about 10 seconds started flashing slowly.
    Now, when I use the fob and press the lock button, I hear the pektron relay clicking, doors do not lock, and and also no rapid flashing of the alarm led, however after 10 seconds the led does start with slow flashing.
    When I lock the car with the key manually, also central lock does not work, the passenger door stays open, but the alarm does now work with fast and slow sequence.

    So what I can rule out here : lock motor, fob battery, reception of fob signal (fob relays clicks both at pushing lock and unlock fob keys).
    I have found a complete wiring schematic, next is to test the micro switches of the lock.

    For the MOT the garage did some repairs on the wiring loom for the brake light in de boot, near the hinge the wire was broken. I checked the boot light, still works, but if the boot lock microswitch is somehow connected to the pektron, could it be that a broken wire is preventing the lock because the pektron thinks the boot is open ?

    2 years ago I replaced all my pektron relays with good quality new ones, even made an how-to, so I am having a hard time believing this is again broken, but surely I will check, or just send the unit to Paul.
    It is a weird fault, just appeared out of nowhere, worked fine, until just at once, could not lock the car anymore. No warning of intermittent failure.

  • Thanks, that is clear. I guess the keyfob has a transponder. For my other car, an Audi A2, this works about the same: only new keys can be programmed, not keys from a donor audi. My way around that is to remove the old glass-housed transponder from the key, and put in a brand new ID 48 transponder, that works. The transponder is very cheap on ali, only a few euro's, whereas a new key from the dealer is more than 100 euro.
    Looking at the MGTF keyfob inside there is a different kind of transponder, not a glass one, but the coil is soldered, or glued, on the small PCB so it might well not be an ID48, but a different type.
    Anyway, having two sets of fobs, beloning to each pektron, is very inconvenient, so therefore the clone idea.
    So I will give Paul an email, see what he thinks about it. I am a bit worried about the package getting lost in the postal services, perhaps I can insure it at a value needed for a complete new set: ecu, pektron, 2 fobs.

    SInce I am bothered now and again with pektron issues, I would like to have a spare one for easy swap.
    Now I have seen that some clever guy invented pscan, to read an program functions in the pektron.
    So I am thinking of ordering one, but a few questions for those who already are know to the pektron quality.
    Is is possible to swap a pektron unit for a donor pektron unit coming from another TF?
    What programming needs to be done to get it working. I guess keyfob match, but does the donor pektron need to be programmed to the ecu, and possible other units ?
    Best would be to just clone the existing pektron to the donor, (plug and play) would that be possible with pscan ?

    Another alternative for using pscan would be to send the unit to a UK based company for cloning, but the risk that the postal services get the package lost, is too high. And being in the Netherlands, it is quite a long drive to physically visit such a company and cloning is also probably not something you can wait for. So therefore the DIY option seems safest. I know my way around in VAG ecu's with VADIS so not new to this kind of work, but MG units are new to me.

  • Hi Richard, Welcome to the forum from Theo, also Netherlands (Leiden). I have my TF135 2005 since 2016. My list of repairs: issues with water ingress in rain, alternator failure, 3x new head gasket, leaking transmission, Pektron ECU relays, engine head rebuild, modified head gasket, bolts and sump rail, new engine cilinder liners, new suspension arms, and the car has had a dinitrol anti rust treatment.
    Next on the list is repair of the central locking system, solve some issues with my MG garage due to poorly performed repairs, these are urgent. After that repair of audio installation, new back window, installation of Optima battery, and I think on the long run it could use a set of new fuel injectors and throttle cable is sticky, and I would like to have the boot and bonnet electrically opened, in case the cables should break. The car is not as new but is good enough to drive on a nice sunny day.

    The central locks of my TF will unlock with the keyfob, but won't lock. Keyfob has new battery, also the alarm is set when I press the lock button. Also locking with the door key only locks the drivers door, not the passenger door, and also the alarm is set.
    2 years ago I have replaced the pektron relay for central locking, I would guess this is still not worn out, so that leaves the door lock mechanism itself.
    Before disassembly I would like to test it on the vehicle, and to to that I need the color wiring for the lock motor. There is a 6 pin connector, and probably 3 of these are for the motor. The car wiring loom side has different colors from the lock-loom side. I have made pic's of the situation.
    Anyone already done such a repair, and knows how to test the lock mechanism on the car ?

    Thanks for helping

  • The ticking has started after the garage has replaced the complete exhaust system due to MOT. Also the ticking gets louder after the engine has heated up, so I think it could be somewhere in the exhaust system. But a new development : on the highway, the ticking got really bad, until it became a loud rattle for a few minutes, I was standing still in the traffic jam. The rattle ended suddenly just like something broke off. After that the ticking noise has almost diminished, still there when the engine is hot. I didn't come around to doing a good diagnoses,
    I have also issued a complaint against the garage because the repair in general was performed poorly, they had to replace front and rear suspension arms due to MOT, but the car is now makes a cracking sound at every corner, and they had to remove the front bumper to get to the suspension arm bolt, and at re-installation they mounted the bumper crooked, not aligned with the rest of the car, also sits against the headlights while there should be a few mm space, and bolts of the inner wheel arch covers are missing. The garage did not react to my complaint so I issued a complaint at our Dutch Bovag, I want to have these issues repaired in a decent way preferably by another garage, then also the ticking noise can be investigated. And mind you, this has been an official MG/Rover garage until MG had gone bankrupt, and they still sell and service MGF and TF's, so I was mindblown about this poor quality.
