CQ1080495 LAUBER Rectifier Magirus-Deutz D-Series Bosch Alternator – The Correct 6-Diode Rectifier for 14V Systems
Your Magirus-Deutz D-Series charges fine at cold idle. Then it stops charging when hot. Or the battery light glows dimly instead of switching off. That points to one component: the rectifier. A failing rectifier lets AC current leak into your DC system. Consequently, your batteries overheat, your lights flicker, and your voltage regulator works twice as hard. You do not need a full alternator. You need CQ1080495 LAUBER Rectifier
This LAUBER rectifier is a brand-new 6-diode unit, manufactured specifically for Bosch alternators fitted to the Magirus-Deutz D-Series. At just £21.99, it restores full DC conversion without replacing serviceable components.
Why the CQ1080495 LAUBER Rectifier Fails Before Anything Else in a Bosch Alternator
Bosch alternators from the D-Series era share a common weakness. The rectifier diodes degrade from heat cycles over time. One diode shorts. Then the alternator produces AC ripple. Your batteries suffer first. Then the regulator fails.
However, the rest of the alternator often remains perfectly healthy. The rotor still excites. The stator windings test clean. The bearings spin smoothly. Changing the whole alternator for a £22 rectifier makes no financial sense.
CQ1080495 solves exactly this problem. LAUBER builds these rectifiers to Bosch’s original specifications. Six high-quality diodes. Correct heat sink dimensions. Direct bolt-on fitment.

Before ordering, remove your alternator and check the Bosch casting number. Use this Bosch alternator identification guide to confirm fitment. Then order CQ1080495 with confidence.
What CQ1080495 LAUBER Rectifier Means for Your Repair
LAUBER is a respected European manufacturer of alternator and starter components. Based in Poland, they supply workshops across Germany, France, Italy, and the Benelux countries. Their rectifiers are known for correct diode matching and proper heat sink material — two factors where cheap imports cut corners.
A rectifier is not a complex part. But quality matters. Cheap rectifiers use underrated diodes. Those diodes fail at high temperature. Then you tear down the alternator again. LAUBER rates every diode for continuous 150°C operation.
So, when you fit CQ1080495, you fit a component built for commercial vehicle duty cycles. Not a generic part from an unknown factory.
Three Signs Your Magirus-Deutz Needs This Rectifier Today
Battery light stays on dimly – The rectifier leaks AC current. Your dashboard light sees that ripple and stays illuminated. A new CQ1080495 kills the ripple. The light goes off.
Batteries boil or sulphate quickly – AC ripple destroys batteries. You replace batteries every 12 months instead of every 60 months. That costs far more than £21.99.
Alternator whines or growls electrically – A shorted diode creates a distinct electrical noise through the charge lead. The noise changes with engine RPM. Swap the rectifier. The noise stops.
How to Test Your Rectifier Before Buying
Grab a multimeter. Set it to AC volts. Probe the alternator output terminal with the engine running. You should see less than 0.5V AC. Anything above 1.0V AC confirms rectifier failure. CQ1080495 fixes that.
You can also test diode continuity with the alternator off. A shorted diode reads continuity in both directions. A healthy diode reads one way only.
Installation – Do This, Not That
Remove the alternator from your Magirus-Deutz. Take off the plastic cover on the back. Remove the three rectifier mounting screws. Desolder or cut the three stator phase wires. Remove the old rectifier.
Place CQ1080495 into position. Re-solder the stator wires using high-temperature solder (minimum 60/40 tin/lead). Reinstall screws. Reassemble.
Do not use standard electronic solder. It melts at 70°C. Your alternator runs at 120°C. Use proper alternator-grade solder or crimp connectors rated for high temperature.
The Cost Case — Why £21.99 Saves You Hundreds
A full alternator for a Magirus-Deutz D-Series costs £350–£500. A replacement battery costs £120–£180. Voltage regulator costs £40–£60.
CQ1080495 costs £21.99.
Fitting this rectifier at the first sign of AC ripple prevents every single one of those other failures. A £22 part protects £600 worth of components. That is not a repair. That is an investment.
