Peugeot 206 and 207 Teves MK70 (ATE) ABS Pump Repair: Warning Lights, Codes and a Lasting Fix

This page covers the MK70 as fitted to the 206 and 207. The unit in general, across every car it was fitted to, has its own Teves MK70 ABS pump repair page, and both belong to our wider range of ABS unit repairs.

What does a failing Teves MK70 unit do to a 206 or 207?

Five faults account for most of the Peugeot MK70 units that reach our workshop. Taken one at a time, each looks like it could be something smaller on the car. Taken together, they usually describe one unit.

• ABS lamp on. The module has found a fault it cannot live with and has switched anti-lock control off.
• ESP, ASR, TCS or DCS lamp on. Peugeot and different diagnostic tools use several names for the stability and traction functions. All of them are run by the MK70, so they stand down when it does.
• A brake pressure sensor fault stored, most often C1301 or C1302.
• Wheel-speed sensor faults that return after the sensors themselves have been checked.
• No communication, where a diagnostic tool cannot reach the ABS unit at all.

These are the faults we find most often on these units, not every fault the MK70 can produce. If your car shows something else alongside an ABS or ESP lamp, it is still worth putting on the repair form.

With the ABS lamp lit, normal braking usually remains, so the 206 or 207 will still stop when you press the pedal. What has gone is the anti-lock control and, with the ESP lamp on too, the stability and traction assistance — the help that matters on a greasy roundabout or in an emergency stop. Have the car checked promptly rather than getting used to the lamps. Our explainer on what an ABS pump does shows how the unit behaves when it is healthy.

The lamp also counts at the MOT. Under the DVSA’s inspection rules, an ABS warning lamp that stays lit after the start-up check is a major defect on any vehicle first used on or after 1 July 2003.

Which fault codes does the MK70 leave on a 206 or 207?

Scan tools do not all word ABS faults the same way, so treat the table as a map of the usual pattern. Each row says what the reading suggests on a Peugeot MK70, and where it stops short of proof.

C1301 and C1302 are the best-known signature of this unit, and the pressure sensor behind them is explained in full, alongside the Citroen and Renault models that share it, on our Citroen, Peugeot and Renault brake pressure sensor page.

A silent module needs the car’s side of the connection cleared before the unit is blamed, and our ABS no-communication guide sets out what to look at and in what order. A single wheel-speed code with nothing else lit is more often the sensor than the pump; our wheel speed sensor guide covers that check.

Why does the MK70 give up, and why is it mistaken for a sensor or wiring fault?

The MK70 inherited its main weakness from the MK60 before it. Both units have the brake pressure sensor built in, and in both it carries a low maximum pressure rating. Every firm stop sends a pulse of brake pressure through a sensor that was given little headroom, and a 206 or 207 has been through a very large number of those stops by now.

The rest of its surroundings add to the load. The unit is bolted into the brake circuit in the engine bay, so it heats and cools with every drive, takes the vibration of every road surface and runs its pump whenever ABS or ESP intervenes. Brake fluid that has gone past its change interval draws in moisture, and the MK70 sits in the middle of that fluid.

The way the failure shows itself is what sends people down the wrong path. The MK70’s control module is where every wheel-speed signal and the brake pressure reading are judged. As the unit degrades, it can reject a healthy wheel sensor, disagree with a perfectly good brake light switch, or drop off the diagnostic network entirely. Each of those looks like a smaller fault on the car, and each tends to be fixed in turn before the unit comes under suspicion.

It is also why a like-for-like replacement is a weak answer on this unit. A new or second-hand MK70 carries the same internal sensor design, so the car goes back to the start of the same countdown.

Is your 206 or 207 fitted with the MK70 or the earlier MK60?

The MK70 was fitted to the Peugeot 206 and 207 as the combined ABS and ESP pump and control unit. It was not the only ATE unit on these cars. Some 206 and 207 models carry the earlier MK60, which fails in a very similar way and is covered on the pressure sensor page linked above.

The model name and year only narrow it down. The part numbers on the unit’s own label identify it exactly, and they are what we match against. If you are not sure what you are looking at, add the numbers to the repair form or send them to us, and we will confirm which unit it is before it comes off the car.

Repair your own MK70, take an exchange unit, or buy a replacement?

Once the MK70 is confirmed as the fault, you will usually be offered a replacement. There are four routes in practice, and they differ most in what ends up on the car and what happens at refit.

Coding is the step people underestimate. A unit that has never been on your car knows nothing about it, and setting it up needs equipment able to talk to the car at manufacturer level. Your own repaired MK70 avoids that entirely, and our exchange units calibrate themselves to the car they are fitted to.

Exchange suits a 206 or 207 that is needed on the road: one of our units goes out, and yours comes back to us in its place.

What happens once the MK70 leaves your car?

We repair the unit, not the car. Your garage takes the MK70 off and sends it to us, and this is the route it follows from there.

1. Codes, lamps and label on the form

   Tell us whether it is a 206 or 207, which lamps are lit, any codes and the numbers on the unit’s label, and whether you want your own unit repaired or an exchange. We confirm the job before anything is unbolted.

2. The unit comes off at your garage

   Your garage disconnects the MK70 and posts it to us, well padded and with the pipe ports sealed so nothing gets in on the way.

3. The fault is reproduced on arrival

   The unit is tested before any work starts, so the repair is based on what it does on our equipment rather than on a stored code alone.

4. Repaired, corrected and run under load

   The fault is repaired and the unit modified so the known design weakness does not return. It then runs on our in-house Hardware-in-the-Loop platform, which recreates the heat, vibration and load it faces under the bonnet.

5. Refitted, bled and cleared

   Your own unit goes back on with its coding intact; an exchange unit calibrates itself. The brake circuit was opened for removal, so your garage bleeds the brakes, clears the stored codes and checks the lamps go out.

We have repaired thousands of these units, which is why we now keep MK70s in stock for exchange rather than making every customer wait for their own.
